| 摘 要： | 为了研究土钉墙的工作性能,分析其受力状态和作用机理,结合某铁路高陡顺层石质路堑土钉墙防护工程实际,进行了现场试验。通过在不同排数土钉的不同位置上埋设钢弦式钢筋计进行使用阶段的性能测试,得出了土钉拉力随土钉长度和时间延续的变化规律、土钉墙潜在的破裂面位置、土钉墙土压力沿墙高的分布规律等有益的结论,可为类似工程的设计与施工提供参考。

| Abstract: | The b ehaviors and stren gth of soil nailing are studied by field test, based on the engineering performa nce of the high and steep bedding stone cutting protected with soil nailing. The force of nail on different row and different location soil nailing is meas ured with vibrating wire strain gauge. Some conclusions are elicited, such as th e variation of nail force with nail lengt h and time, the potential sliding surface and the distribution of eart h pressure on soil nailing wall. The test results can be used as reference for the design and construction of soil nailing wall. |
