| 摘 要： | 为向建设中的西昌-攀枝花高速公路桥梁桩基础设计提供参考（该高速公路沿线约90km路段通过岩性软弱、遇水易泥化和崩解的昔格达岩层），在攀枝花地区新九和安宁河流域德昌蒲坝的昔格达岩层中对13根灌注桩进行了单桩轴向静载试验，研究了桩的承载力和影响承载力的因素。结果表明，昔格达岩层可以作为桩基础的持力层，但应保证桩的施工质量． |

| Abstract: | To provide a reference for the design of pile foundations of bridges on the Xichang- Panzhihua expressway being constructed, the static loading tests and researches on the axial bearing capacity of 13 cast-in-situ piles set in Xigeda-rock were carried out at Xinjiu in Panzhihua and at Puba in Dechang. Xigeda-rock is an extremely soft rock with the special behaviors of softening, mashing and collapsing due to water, and this kind of rock abounds in a region as long as 90 km along this expressway. The experimental and research results show that Xigeda-rock can be used as the ground of pile foundations, and the construction quality is extremely important to their bearing capacity. |
| Keywords: | xigeda-rock soft rock cast-in-situ pile static loading test bearing capacity |
