| 摘 要： | 根据成桩工艺、土性状态查表确定桩周土侧阻极限标准值时，如不考虑长径比及土层相对桩身的位置，将会产生较大的误差，同时还可能对嵌岩桩的桩工机理产生误解。通过实例分析，说明了在确定大直径软岩嵌岩桩桩周土侧阻时应注意的问题。

| Abstract: | Biggish error will be brought in ascertaining the bearing capacity of rock-socketed pile casted in soft rock when taking soil around pile and manufacture technology into account only. Ignoring length-diameter ratio of pile and stratum located along it, we may misapprehend the mechanism of the pile. Based on the field static load experiment, problems on ascertaining the bearing capacity of rock-socketed pile are analyzed in this paper. |

| Keywords: | rock-socketed pile bearing capacity shaft-resistance base resistance soft-rock |
