山区桥梁桩基自平衡试验

Self-balance Static Load Test of Pile Foundation for Bridges in Mountain Area

山区地形地势高低起伏,静载试验中利用传统的堆载法和锚桩法检测桩基难度较大,且不经济实用。通过总结近几年在湖南进行的自平衡试桩工程,系统性地介绍自平衡试验,证实了其实用性、合理性及可靠性,为类似地区桥梁桩基测试提供一定的参考。

Due to the rising and falling of land, it is usually very difficult, uneconomical and im- practical to carry static load test of piles in mountain area by kentledge system or anchorage system. The self-balance static load test carried out in Hunan were summarized in recent years. The self-balanced method were introduced systematically. It＇s proved that the self-balanced method is practical, reasonable and reliable. It provides some references to pile test of bridges in the similar district.
