深厚软土层中超深基坑地下连续墙支护的设计与实践

摘要

To take the super-deep foundation pit support in thick soft soil on the first-rank terrace of the Yangtze River in Wuhan as an example, according to the specific engineering geology and surrounding construction environment, we introduce the technical solution plan of underground continuous wall support, the specific parameters of construction and monitoring. The results of practice show that our solution plan not only ensures the safety of foundation pit and the surrounding engineering, but also saves money and time. It can be beneficial to similar foundation pit supports.%以武汉市长江一级阶地深厚软土层中某超深基坑支护工程为例，根据具体工程地质条件及周围环境条件，详细介绍了地下连续墙支护技术方案、施工技术要点与监测技术要求。实践表明，该方案不仅保证了基坑支护结构及周边环境的安全，而且降低了经济成本，节省了工期，可为类似基坑工程的设计与施工提供参考。
