【摘要】 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。更多还原

【Abstract】 Due to the site restriction during the Shenzhen River training project,a reinforcement retaining wall with 7. 7m high is built. In order to know the distribution of the wall lateral displacement,base earth pressure,the wall back earth pressure and the reinforcement tensile force,a in-situ test is performed. The test results including lateral displacement,base stress,lateral earth pressure,variation of reinforcement tensile forces will be a valuable reference for the similar design and monitoring.更多还原
