地下连续墙的受力状态及计算图式分析

Analysis of stress state and diagram of diaphragm retaining wall

在地下连续墙工程现场观测的基础上,对其受力状态进行了分析探讨。指出单元墙段是呈双向弯曲受力状态。因而按现行设计(单向受弯)的配筋计算应做适当的调整。在用筋总量不增加的基础上,使墙体结构设计更加合理、完善、经济、可靠。

Based on the field observation in construction of diaphragm retaining wall, the stressing state is analyzed. It＇s proposed that the element wall is stressed by two-way bending. Therefore, reinforcement calculation by the current design specification （one-way bending） should be regulated properly to make design of the wall structure more reasonable, perfect, economic and reliable, while the total amount of reinforced bars is not increased.
