深基坑工程施工过程灾变分析及抢险救灾对策研究

Analysis on Disasters of Deep Foundation Pit Engineering in Construction Process and Countermeasures for Emergency Rescue and Disaster Relief

以泰州港靖江港区新港作业区江苏省煤炭物流靖江基地项目为例,对其二期工程陆域道堆施工项目在施工过程中的致灾因素进行分析,在此基础上,提出了施工过程中的各类抢险救灾应急对策。以基坑围护监测数据为主要依据,对基坑施工期间的灾害源进行比对分析及等级划分,并对泰州港靖江港区不良地质条件下的基坑围护结构设计和施工措施提出了建议,为相关基坑工程的施工控制及抢险救灾应急方案提供参考。

Taking Jingjiang base project of coal logistics in Jiangsu Province in Xingang operation area of Jingjiang port area of Taizhou port as an example,the factors causing disasters in the construction process of the land road pile construction project of the second phase of the project are analyzed,and on this basis,various countermeasures for emergency rescue and disaster relief are proposed.Based on the monitoring data of the foundation pit enclosure,the disaster sources during the construction of foundation pit are compared,analyzed and graded,and the design and construction measures for the foundation pit enclosure structure under the adverse geological conditions of Jingjiang Port Area of Taizhou Port are put forward.It provides a reference for the construction control and emergency rescue and disaster relief plans of related foundation pit projects.
