深基坑中水平封闭框架支撑体系的设计和工程实践

Design and Engineering Practice of Horizontally Sealed Frame Bracing System Used in Deep Foundation Pit

这是一种全新的基坑围护方法,即将基坑围护在结构上优化设计成为一个受力性能良好的封闭框架,并采用钢筋混凝土现浇制作,以提高围护的整体刚度。

This is a brand -new method of pit enclosure, that is , to enclose foundation pit within a sealed frame which is structurally designed with optimized load - bearing capacity and placed with cast - in - situ reinforcement concrete so as to improve the integral rigidity of enclosure.
