摘要
中国电子科技大厦属深大基坑支护工程。考虑到工程周边环境条件极其复杂,采用了桩锚、土钉、复合土钉和土钉+桩锚的联合支护方案。介绍了地下水控制技术,不同地段的支护设计方案以及施工中遇到的问题和采取的措施。结果表明,各侧边坡位移很小,均满足设计要求,地下水位也得到有效地控制。
China Electronic Science and Technology Plaza is a deep and large foundation excavation engineering.Considering complicated conditions of project,the combined supporting design including pile-anchor,soil nail,composite soil nailing and combination of soil nailing with pile-anchor is adopted.Underwater control technology,support designs of different sections,problems and corresponding solving measures are introduced in detail.The result indicates that the displacement of slope is small,which can meet design requirement,and the groundwater level is under control.
