Analysis of strengthening effect of the rui ' an part of wenzhou expressway soft foundation by vacuum preloading method 甬台温高速公路瑞安段真空预压软基处理效果分析
This paper introduces in detail the mechanism of consolidation in the preloading method combining vacuum with stack - load , and puts forward the calculating model 本文较为详细的介绍了真空联合堆载预压法的加固机理,提出了真空联合堆载预压法的稳定计算模型。
Among soft - base improvement methods , prefabricated drain preloading is one of the most popular vertical drain methods . it is developed from sand drain preloading method 塑料板排水预压法是在砂井排水预压法的基础上发展起来的,是一种行之有效的软基加固方法。
After analyzing the 5011 properties and treatment technologies in different wharf areas , it is suggested that the vaccum preloading method and dynamic compaction method are used to treat the soft foundation 结合土质特点等因素,分区进行不同工艺的分析,建议真空预压法和强夯法进行地基处理。
The conventional stack - preloading method which we use at present can not meet the requirement of stabilization , time limit of construction and the settlement after completion of works , so a new kind of technique is to be introduced to soft soil treatment 高速公路的建设必须首先对这种地基进行处理。目前,常规堆载预压法很难满足施工稳定、工期和工后沉降的要求,必须采用新的技术措施进行处理。
