　　为更深入地研究桩板墙背侧的土拱效应，分析其土压力荷载的作用规律及传递特性，进一步揭示桩板墙土拱效应与荷载分配之间的联系，采用现场大型试验及室内模型试验开展相关的监测研究工作。基于对土拱结构承载机制的认识，将作用于桩背侧与桩间挡板中部土压力的比值作为衡量土拱效应作用效果的直观标准。在某一自然边坡上，设计施工桩板墙堆载试验的模型槽，在挡土板与抗滑桩背侧分别安装土压力计，并开展持续21 d的现场试验监测。现场试验结果表明，随着时间的发展，该土压力的比值呈现先增加后趋于稳定的特点，时间效应相对较显著。还设计多工况室内模型推桩试验，为深入分析桩板墙背侧土拱效应与土压力传递特性之间的关系，试验重点对挡板刚度、桩间距、填料性质和挡板布置方式对桩板墙土拱效应的影响进行对比研究，并揭示被动状态下桩板墙背侧的土压力传递特性。

In order to further study the soil arching behind the sheet-pile wall and analyze the earth pressure load regulation and transmission characteristic, the field large-sized test and indoor model test are carried out by monitoring research. In addition, the test results can further reveal the regularities about soil arching and load distribution. Based on the comprehension of the action mechanism about the soil arching structure, the ratio between the earth pressure on the back side of pile and pressure on the breast board is regarded as a standard which is used to assess the arching. A test model box is designed and constructed in order to load behind sheet-pile wall at a rock slope. The earth pressure cells are fixed on the dorsal surfaces of sheet and piles to test the earth pressure during future 21 days. The test results show that the earth pressure ratio increases firstly and then tends to be stable as the development of time; therefore, the time effect is relatively obvious. In addition, multiple test conditions are also designed and done to make further analysis about the relationship between the soil arching and transfer behavior of earth pressure behind sheet-pile wall. The comparative researches are done about different baffle rigidities, pile spacings, filler properties and arrangement effects of sheets, which explains the transfer behavior of load behind sheet-pile wall in the passive soil pressure state.
