在深圳河道治理工程中,由于一侧施工场地环境受到限制,因此采用一座总墙高为7.7m的新型挡土结构——钢带式加筋土挡墙起支挡围护的作用。为了研究挡墙墙体的水平位移、基底土压力和墙背侧向土压力以及拉筋筋带受力的分布规律,对该挡墙的变形和受力情况进行了现场原位观测,得到了水平位移、基底土压力和墙背侧向土压力以及筋带拉力的变化和分布规律,研究结果可供今后类似挡墙结构的设计和研究以及监测提供参考。
In the Shenzhen River Regulation Project, a new type of retaining structure with a total wall height of 7.7m - steel band reinforced earth retaining wall functions as a retaining wall due to the restricted construction site environment. In order to study the horizontal displacement of the retaining wall, the earth pressure on the base and the lateral earth pressure on the dorsal wall and the stress distribution of the tendons, the deformation and stress of the retaining wall were observed in situ. Horizontal displacement, base soil pressure and dorsal earth pressure on the dorsal wall and the tensile force of the tendons. The results of this study can provide references for the design and research of similar retaining wall structures and their monitoring in the future.
