摘要: 在试验基础上建议了一个预测冲击荷载作用下饱和软粘土残余变形的计算模式,该模式考虑了周围压力、冲击能大小、冲击次数和冲击遍数等几个因素.对计算模式的验证表明,预测值与实测值吻合较好.该模型可用于动静结合排水固结法处理软基时的变形计算.

Abstract: Based on laboratory test results, a model for predicting the residual deformation of soft clay under impact loading is proposed in this paper, which fits well with other test results.This model, considering several factors which affect the residual deformation such as confining pressure, impact energy and the number of impacting, can be used for the deformation prediction in the treatment of saturated soft clay by the drainage consolidation method of combining static and dynamic loading.

Key words: model, residual deformation, soft clay
