The spiral sheet metal carry the lotus test to be apply in the bearing power test of the deep foundation soil and water table following foundation soil extensively because the ability goes into the surface of earth is following the certain depth area curve carry on test , according to the element that the spiral sheet metal carries the lotus test , through contrast with plate load test , the spiral sheet metal carries the lotus test to be applicable to the shallow storey foundation soil equally , the size of the spiral sheet metal time area concentration diagram is not big to the test result influence , the spiral sheet metal carries the bearing power of the lotus test assurance to no longer carry on the depth area curve redress
摘要螺旋板载荷试验因能旋入地面以下一定深度进行试验而广泛应用于深层地基土及地下水位以下地基土的承载力测试，根据螺旋板载荷试验的原理，经与平板载荷试验对比，螺旋板载荷试验同样适用于浅层地基土，螺旋板面积的大小对试验成果影响不大，螺旋板载荷试验确定的承载力不再进行深度修正。
