重庆某工程位于长江与嘉陵江交汇处。其在人工挖孔桩施工中，遇到了很厚的卵石层。卵石塌方严重，紧挨卵石处护壁成悬空状态，危及到了孔内作业人员的人身安全，导致无法成孔。本文主要介绍了卵石人工挖孔桩施工技术成孔经验，可供类似工程借鉴。

A project in Chongqing is located in the Yangtze River and Jialing River interchange. In the construction of ma-nual bored pile, builders encountered a thick layer of cobbl-estone. The cobblestone col apses seriously, and the retaining wal closely to the gravel is at hanging state, which endangers workers’ safety, thus the holing is a failure. This paper mainly introduces the experience of construction technology of man-ual bored pile of cobblestone which can be used for reference for the similar project experience.
