自平衡法在大直径钻孔灌注桩检测中的应用研究

进入新世纪，我国东南沿海经济发展快速，区域特点为软土地质、河流众多，桥梁建设不可避免，而桥梁的安全离不开钻孔灌注桩的支撑。以某软土地区某桥梁的钻孔灌注桩承载力检测为例，在满足项目要求的基础上比选出了自平衡法检测方案，并为项目的建设提供了支撑，可以为类似项目的大直径、大吨位钻孔灌注桩承载力检测方案设计提供一定价值的借鉴。

Research on Application of Self-balancing Method in Detection of Large-diameter Cast-in-situ Bored Piles

The research on the application of self balance method in the detection of the bearing capacity of bored piles has entered the new century. With the rapid economic development in the southeast coast of China, the regional characteristics are soft soil geology, numerous rivers, and bridge construction is inevitable. The safety of bridges cannot be separated from the support of bored piles. Taking the bearing capacity detection of bored pile of a bridge in soft soil area as an example, this paper compares and selects the self balanced method detection scheme on the basis of meeting the project requirements, and provides support for the project construction, which can can provide some valuable reference for the design of bearing capacity test scheme of large-diameter and large-tonnage bored cast-in-place pile of similar projects.
