摘要
以现场实测数据为依据,对真空预压法和堆载预压法两种地基处理方式进行比较。简述了两种地基处理法的发展史及作用机理;通过现场实测沉降曲线对比了两种预压法下土体沉降速率;通过静力触探比贯入阻力曲线对两种方法的加固效果进行比较;通过Asaoka拟合法及理论计算对两种方法的沉降进行预测及对比。
This paper makes a comparison of vacuum preloading method and surcharge preloading method based on the on-site measured data. The development histories and the preloading mechanism of the two methods are introduced. The field measured s-t curves are introduced to compare the settlement rate of the two methods. The CPT penetration resistance curves are also used to compare the reinforeemem effects of the two methods. The ultimate settlements of the foundation are predicted through asaoka fitting method and calculation.
