In　this　paper,　the　state-of-the-art　of　studies　on　the　liquefaction　of　saturated　soils　are　reviewed,　including　the　mechanism　of　the　soil　liquefaction,　the　influential　factors　of　the　seismically　induced　soil　liquefaction,　the　approach　of　estimating　and　analyzing　the　seismic　hazard　of　the　soil　liquefaction,　and　the　characters　of　the　post-liquefaction　soils.　Some　works　on　the　soil　liquefaction　induced　by　blasting　are　also　introduced.　Then,　after　analyzed　these　works,　some　intending　research　works　are　proposed,　such　as　the　dynamic　constitutive　relation　of　the　soil　skeleton,　the　effect　of　the　Rayleigh　wave　to　liquefaction,　the　influence　of　the　structure-soil　interaction　on　liquefaction,　the　character　of　the　post-liquefaction　soils,　the　building　settlements　due　to　liquefaction　and　blasting-induced　liquefaction,　and　so　on.
