| 摘 要： | 在淤泥层较厚持力层为岩石地基的地质条件下,常采用冲、钻孔灌注桩嵌岩,但在施工过程中塌方塌孔严重、安全性差,如何突破预制桩本身具有无法穿过孤石和滚石的特性,实现嵌岩是工程中需要研究的问题。结合实际工程设计与施工,根据工程地质和荷载情况,通过采用不同的桩体及桩靴形式,成功实现预制桩在岩石地基中嵌岩的目标。

| Abstract: | It is common to use punching cast-in-place pile or drilling one to embed into rock under the geologic circumstances that silt stratification is thick and supporting course is rock foundation.However,safety issues including cave in and collapse arise in the process of construction.Therefore,breaking through the bottleneck that the precast pile can not cross the boulder and stonefall to realize rock embedment is an issue to needing study in the engineering.Combining the engineering design and actual construction,we adopt different types of piles and pile shoes and realize the embedment of the precast pile in the rock foundation. |
