静载试验是模拟建筑荷载条件确定试验对象承载力的原位测试方法,将荷载分级施加到试验对象上,同时观测分级荷载作用下的沉降量,最后绘制荷载与沉降等关系曲线,依据规范确定承载力特征值。本文采用静力载荷测试仪测定挤密碎石桩的承载力,以复核该桩的承载力能否满足设计要求。

The static load test belongs to in-situ test method for determining bearing capacity of tested object by simulating construction load conditions. Load is applied on tested object at stages. Meanwhile,settlement under graded load effect is observed. Finally,relation curve between load and settlement,etc. is drawn. Bearing capacity characteristic value can be determined according to specification. In the paper,static load tester is adopted for testing bearing capacity of extruded gravel pile,thereby checking whether the bearing capacity of the pile can meet design requirement or not.
