摘要
介绍了在深厚淤泥层中采用地下连续墙加内支撑支护系统作为深基坑支护结构施工的成功经验,并探讨在该地质条件下地下连续墙施工、降水、土方开挖所采取的一些关键技术措施。在施工中,还采用了先进的监测技术及信息化技术,确保基坑施工处于受控状态。其设计、施工经验对本地区深基坑施工具有一定的借鉴意义。
The successful experience of diaphragm wall and internal bracing system for deep foundation pit in deep silt layer is introduced. Some technical measures for construction of diaphragm wall, dewatering and soil excavation are discussed. In the construction, the monitoring technology and advanced information technology are emplyed to ensure that the construction of the foundation pit is in a controlled state. The design and construction experience has certain reference meanings for the construction of deep foundation pits in the region.
