摘要
文章依托深圳市龙华区龙澜大道北延段工程,从综合管廊基坑工程技术标准、安全等级划分等角度出发,对基坑围护结构进行了优化设计,结合工程周边环境特点,提出了集水明排的基坑降水措施,重点剖析了深大基坑土方施工关键节点工艺,研究结果可为类似工程提供一定的指导.
Abstract
Based on Longlan Avenue north extension en-gineering in Longhua District of Shenzhen City,this paper conducts optimization design of foundation pit retaining structure from the perspectives of technical standards and safety level classification of comprehensive pipe gallery foundation pit engineering.Combined with the character-istics of surrounding environment of the engineering,the foundation pit dewatering measures of water collection and open drainage are put forward,and the key node technolo-gy in earthwork construction of deep and large foundation pit is emphatically analyzed.The research results can pro-vide some guidance for similar engineering.
