作为研究复合地基荷载传递规律和沉降的一个重要组成部分,桩体刺入变形量的分析与研究将进一步完善复合地基沉降理论,但目前对于桩体刺入量的研究并不多。对现有桩体向垫层刺入量计算方法进行了分析,指出不足之处,提出了更为合理的刺入量计算方法。通过与现有计算方法的比较,表明了方法的合理性。与模型试验结果进行了比较,证明了其方法的适用性。 As an important part of studying the law of load transfer and settlement of composite foundation, the analysis and research on the deformation of pile penetration will further improve the settlement theory of composite foundation. However, there is not much research on penetration of pile. The method of calculating the piercing amount of the existing pile to the cushion was analyzed, the inadequacies were pointed out, and a more reasonable calculation method was proposed. By comparing with the existing calculation methods, the method is proved to be reasonable. Compared with the model test results, the applicability of the method is proved.
