On　the　basis　of　the　analysis　of　the　displacement　field　of　buried　pipeline　around　the　two　foundation　pits,　the　protection　measures　of　buried　pipelines　during　excavation　of　two　adjacent　foundation　pits　are　innovatively　studied　based　on　3D　FEM　in　this　paper.　Three　methods　used　for　the　protection　of　buried　pipelines,　including　the　soil　improvement　of　passive　field,　side　area　of　pipelines　and　the　bottom　of　the　pipelines,　are　discussed.　The　efficiency　and　effectiveness　of　the　methods　are　analyzed,　along　with　comparison　of　the　advantage　and　shortcoming　of　the　three　methods.　The　study　demonstrates　that　the　methods　of　the　soil　treatment　in　passive　field　are　relatively　cheap　and　reasonable　protection　measures　comparing　with　other　methods　and　some　valuable　conclusions　for　construction　practice　are　also　drawn　from　the　simulation.
