地下综合管廊在不同环境的深基坑工程设计

Engineering Design of Deep Foundation Pit for Underground Utility Tunnelin Different Environments

地下综合管廊是一种现代化、集约化的城市公用基础设施,是促进促进城市可持续发展的必然要求,目前国内关于综合管廊深基坑设计方面的研究尚有欠缺。以某城市地下综合管廊为工程背景,综合分析综合管廊深基坑特点,针对基坑周边不同环境的特点,结合基坑特性,在不降地下水的情况下,提出了不同深基坑围护结构设计方案,并得到某城市地下综合管廊工程实际应用,为同类工程提供一定参考。

Underground utility tunnel is a modern and intensive urban public infrastructure andis the inevitable requirement to promote the urban sustainable development.At present,the research on the design of deep foundation pit for underground utility tunnel is few in China.Based on the engineering background of an urban underground utility tunnel,the characteristics of deep foundation pit for utility tunnel are comprehensively analyzed.Aiming at the characteristics of foundation pit in the different environments,combined with the characteristics of the foundation pit and under the condition of no lowering the groundwater,the design schemes of different deep foundation pit support structures are put forward,and are practically applied in an urban underground utility tunnel project,which provides a certain reference for similar projects.
