摘要
结合上海市某基坑工程的监测数据对水泥土搅拌桩重力式挡土墙和复合土钉墙这两种支护形式的水平位移和沉降做了比较分析。分析结果表明:两种支护都具有时间、空间效应;在土体卸载后,重力式挡土墙水平位移量大但是稳定快,复合土钉墙的位移持续增加,稳定较慢。
Based on the construction monitoring data of a project in Shanghai, a comparison is made between cement mixing pile gravity retaining wall and composite soil nailing wall for horizontal displacement and settlement . The comparison and analysis show that both bracing types possess time and space effect , after excavation the horizontal displacement of gravity retaining wall increased very quick and stabilized soon , but that of composite soil nailing wall increased continuously and it took more time to be stabilized.
