载荷试验是一般工业与民用建筑物的工程实践中沿用已久的地基勘查方法。在与地基勘查和设计有关的专门科学知识未获得发展之前,载荷试验是获得有关地基质和量两方面资料仅有的勘查方法。近年来,由于钻探取样、土工试验、土力学理论公式等的应用,在工程界中产生了只有利用土工试验所得出的计算指标,结合了土力学理论公式,始能解决。载荷试验不能合适地求出地基的承载力是不正确看法。实际上任何土力学理论公式都是在若干理想的假定下导出来的,土工计算指标则仅与在所给予的试验
The load test is a ground investigation method that has been used for a long time in the engineering practice of general industrial and civil buildings. Prior to the development of specific scientific knowledge related to foundation surveys and design, load testing was the only method of surveying to obtain information on both the matrix and the volume of the ground. In recent years, due to the application of drilling sampling, geotechnical tests, and theoretical formulae of soil mechanics, there have been calculations in the engineering community that have only been derived from the use of geotechnical tests. These have been combined with theoretical formulae of soil mechanics to solve problems. It is not correct to think that the load test cannot properly find the bearing capacity of the foundation. In fact, any theoretical formula for soil mechanics is derived under some ideal assumptions. The geotechnical calculation index is only relevant to the given experiment.
