采用轻型动力触探检测天然地基承载力的若干问题思考

Consideration on Some Problems of Testing Bearing Capacity of Natural Foundation by Using Light Power PenetrationTest

轻型动力触探是一种简单方便、检测速度快、检测成本低的测试方法,目前在施工验槽、填土勘察、软弱填土层勘探、洞穴分布情况勘探中以及地基承载力检测中均有应用。近年来,对于天然地基,部分地区也开始采用轻型动力触探的方法检测地基承载力,并以此来替代载荷板试验。对于轻型动力触探是否可检测地基承载力,是否可以用轻型动力触探检测结果替代载荷板试验作为设计或验收依据,论文对此进行简单探讨,希望可以给从事地基基础工程检测和验收的同行们提供一些帮助。

Because of its simplicity,lightness,high speed and low cost,the light dynamic penetration test(LPT)has become a common method in construction,filling investigation,and finding out the distribution of soft fill and caves.In recent years,for the natural foundation,some areas have also used the light dynamic penetration test foundation bearing capacity,and to replace the load plate test.Whether the light dynamic penetration test can be used to test the bearing capacity of foundation and whether the light dynamic penetration test can be used to replace the load plate test as the basis for design or acceptance is discussed in this paper,hope to be engaged in the ground foundation engineering testing and acceptance of the peer to provide some help.
