载荷试验确定复合地基承载力的分析

Analysis on Loading Tests to Determine the Bearing Capacity of the Composite Foundation

复合地基载荷试验综合反映了桩及桩间土的承载性状.在实际工程中,如何通过载荷试验曲线确定复合地基承载力存在着应用上的一定困难.通过分析各载荷试验确定承载力的方法,提出以沉降变形控制,最好采用相对沉降法和回弹法确定复合地基承载力.

The tests of composite foundation give a comprehensive view on the bearing performances of piles and soil between piles. In actual work, it is rather difficult to apply the loading curve to determining the bearing capacity of the composite foundation. After analyzing various loading tests, the article puts forward sedimentation deformation control and suggests that the relative sedimentation method and the resilience method should be adopted to determine the bearing capacity of the composition foundation.
