| 摘 要： | 针对某工程上部结构的重要性及本市对泥岩缺乏地方经验和必要勘察手段，泥岩深基础承载力取值偏于保守，对其进行深层平板载荷试验和原位侧摩阻力试验．试验表明，勘察提出泥岩极限承载力偏保守，其仍有潜力可挖，且粉砂岩承载力受水影响很大；原位侧阻力试验对于桩—岩（土）间侧阻力测试是可行的，测出泥岩桩侧阻力值很大，是嵌泥岩桩承载力中不容忽视的重要组成部分． |
| 关 键 词： | 泥岩 端阻力 侧阻力 深层载荷试验 原位侧阻力试验 |

| Abstract: | Bearing capacity value of mudstone is conservative, because of being absence of regional experience and essential prospecting methods underlying Nanning region. Deep plate-loading tests and field skin-friction tests had been performed, in view of the importance of structure in certain project. The tests indicated that end-bearing capacity obtained by prospecting means is conservative,and it is impossible to exploit its potentialities. The end-bearing capacity of sandstone is severely affected by permeated water. It is practicable to measure skin friction values from this field test proposed in the paper. The tests indicated the mudstone friction values is very large, and it is important section of bearing capacities of pile. |
| Keywords: | mudstone end-bearing capacity skin friction value deep plate-load test field skin-friction test |
