摘要
以工程实例为背景,详细介绍SMW工法与斜抛撑围护体系在超大深基坑工程中的应用。通过整理分析基坑监测数据,探究变形特点;针对基坑施工过程中的土方开挖、暗浜处理、边坡加固等问题,给出相应的施工措施,并归纳出在该种围护形式下施工所遇到的特有问题。
Taking the engineering example as the background,this paper introduced the application of SMW construction method and oblique bracing envelope system in super large deep foundation excavation in detail. The deformation characteristics were explored by analyzing the monitoring data of the foundation excavation. To solve the problems of earthwork excavation,dark bank treatment and slope reinforcement in the process of foundation excavation construction,the corresponding construction measures were given.Special problems encountered in the construction of this enclosure form were concluded.
