钻孔灌注桩与土钉墙及锚索复合支护的应用

Application of the composite retaining from bored pile,soil nailing wall and anchor cable

近年来,城市发展建设速度快,用于建筑、市政等工程的土地日益紧张,从而导致深基坑周边环境越来越复杂。结合工程实例,简述如何根据不同地质条件及周边情况采取灌注桩、土钉墙、预应力锚索等复合支护措施以确保基坑安全及降低工程造价,并通过监测数据予以了验证,可供类似工程参考。

In recent years,with the rapid development and construction of cities,the land for construction/municipal engineering and other projects is increasingly scarce,which leads to the increasingly complex surrounding environment of deep foundation pits. Combined with an engineering example,the paper briefly describes how to adopt composite supporting measures such as cast-in-place plie soil-nailing wall and prestressed anchor cable according to different geological conditions and different surrounding conditions to ensure the safety of foundation pit and reduce project cost. Through monitoring data to verify,for similar projects reference.
