潮州供水枢纽工程厂房基坑开挖及措施

Foundation excavation and construction measures for powerhouse of Chaozhou Water Supply Control Project

根据潮州供水枢纽工程厂房地基的特点,提出了比较合适的基坑支撑处理措施和开挖方法及控制措施,并结合工程实践对软深基坑开挖施工中应注意的支撑监测、地下水降压、外水内渗处理及基坑内结构物保护等问题提出了解决方法。工程实践表明:文中介绍的方法和措施是科学合理的,对今后类似工程问题的解决将提供有益的借鉴。

Based on the characteristics of the foundation for the powerhouse of Chaozhou Water Supply Control Project, the supporting measures, excavation method and control measures for the foundation excavation is put forward herein, and then the method to solve the problems such as monitoring on the supporting, de-pressurization of the ground water, treatment of the seepage from the outside and the protection of the structures inside of the foundation pit etc. are presented as well. The engineering practice shows that both the methods and the measures are reasonable and seientifie and provide some beneficial references to the similar project as well.
