摘要 ：
This paper aims at analyzing the influence of non-associated flow rule on passive face instability for shallow shield tunnels. The influence exerted by dilation angle on the limit support pressures, the failure zones and partial failure ratios is investigated by numerical simulations. Based on the failure zone obtained from numerical simulation, a log-spiral mechanism is proposed. The upper-bound theorem is employed to acquire the limit support pressures, failure zones and partial failure ratios. The analytical results indicate that dilation angle has a significant influence on the limit support pressure and failure mechanisms. Finally, by comparison with the numerical models and existing analytical models, the results indicate that the proposed log-spiral model has a certain accuracy in analyzing the face instability of blow-out.

摘要 ：
This paper focuses on the ground settlement induced by the construction of a curved shield tunnel. Ground loss and construction loadings are the two factors causing ground settlement, and two corresponding analytical models were developed. First, the ground settlement due to ground loss was analyzed based on 3D image theory. The "integrative gap at shield tail" (IGST) and overcutting gap of a curved tunnel were considered. Second, the ground settlement due to construction loadings was analyzed by modifying Mindlin's solutions. The additional thrust, frictional force, and grouting pressure were considered. Subsequently, a case study and a parameter analysis were conducted. Finally, the obtained solutions were compared with a classical analytical solution, numerical simulations, and monitored results. The proposed model could effectively predict the ground settlement induced during curved shield tunneling.

摘要 ：
This paper focuses on analytical solutions of additional stresses for a curved shield tunnel. General equations of additional stress caused by construction loadings were deduced by rewritten Mindlin solutions, and additional thrust and friction force were considered. In addition, theoretical formulae of additional stress caused by soil loss were deduced based on the three-dimensional image theory, and the actual processes of synchronous grouting and over-excavation were considered. Then, by using a curved tunnel in Zhuhai City, China as a case study, the distribution laws of additional stress along the directions of advancement and circumference were investigated. Under the coaction of construction loadings and soil loss, it was found that the distributions of σx and σy along the advancement direction for curved tunnels are similar to those for straight-line tunnels. However, the soil around a curved tunnel is more likely to yield because the difference between the normal stresses in two directions is greater than that for soil around a straight-line tunnel. Additional stresses caused by soil loss along the circumferential direction for a curved tunnel were found to no longer have the characteristics of strictly axial symmetry. The values of compressive stress σx and σy at the outer side of the curved tunnel were found to be greater and smaller than those at the inner side, respectively. As the curvature radius decreases, the maximum tensile stresses σx and σy for curved tunnels were found to decrease and increase, respectively. Furthermore, an insufficient quantity of injection grouting will trigger detrimental effects to nearby structures during the approaching excavation. © 2020 Elsevier Ltd

摘要 ：
To improve the seismic performance of subway stations built by enlarging two parallel shield tunnels, joints of special structures between prefabricated open-loop segments and cast-in-site main station structures were proposed. Experiments on the low-frequency cyclic loading of full-scale models of joints under different structural configurations were carried out. The seismic performance, such as the load-displacement hysteresis curves, skeleton curves, structural ductility, strength degradation, energy dissipation, strain of the cable-stayed bars and failure modes, were studied. The results showed that compared with the pre-embedded connector joint, the preembedded steel plate joint had advantages in terms of the mechanical stability, intensity, stiffness, energy dissipation capacity and ductility performance. However, the relative displacement between the segment and wall column of the pre-embedded steel plate joint was larger than that of the pre-embedded connector joint. Both types of joints had a full hysteretic circle, good ductility nature, energy dissipation ability, and stable elastic and elastic-plastic deformation. The cable-stayed bars did not yield in the stretch area when the joints failed. Both of the joints could meet the performance requirements of strong joints and weak components.

摘要 ：
Rainfall infiltration is one of the main triggers of slope failure. Based on the upper bound theorem of limit analysis, this work presents an analytical stability analysis of a 3D vertical cut slope subjected to rainfall infiltration. An analytical model that can directly provide pore water pressure change at any depth and time is adopted to calculate the time-dependent matric suction and shear strength of unsaturated soil during the rainfall infiltration process. Thereafter, based on a 3D rotational failure mechanism of a slope, the energy balance equation is built, and the factor of safety (FoS) of the slope is consequently determined in conjunction with the strength reduction technique. The influences of the 3D characteristics of the slope and rainfall patterns on both FoS and failure pattern of the slope are investigated. It is found that the 3D characteristic of slope is a key factor which determines the FoS of slope. Different rainfall infiltration patterns lead to diverse variation rules of both the FoS solutions and the critical failure patterns of slope. However, these rainfall patterns with a same accumulated rainfall result in the same FoS solution of slope at the end of rainfall infiltration. The present work may provide guidance on the stability analysis and preliminary design of slopes subjected to rainfall infiltration.

摘要 ：
为建立更为灵活实用的地铁工程风险分析过程,利用基于性能的地震工程(performance-based earthquake engineering,PBEE)理念提出了基于性能的风险分析(performance-based risk analysis,PBRA)方法.该方法的分析流程主要包括性能风险损失等级确定、力学响应分析、风险损失等级分析、性能风险分析4个主要部分,分析结果以性能风险等级矩阵的形式表示.与以往分析方法相比,PBRA方法具备以下优势:1)PBRA方法紧密结合风险演化的物理过程,实现了风险的全阶段量化分析;2)PBRA方法将性能水平与风险损失相对应,从而降低了确定风险损失的难度,并且使得分析结果更符合工程需求;3)PBRA方法集成了土木、交通、环境、经济、社会等众多学科的经验、理论与技术成果,为风险分析智能化创造了必要条件.
