摘要
武汉市新区梅子路广泛分布湖积相软土,采用真空联合堆载预压法处理地基。试验段长300 m,分三个试验区共设6个测试断面观测地面和地基深层的变形。结合试验成果,建议真空联合堆载预压地基按堆载条件下附加应力和真空预压条件下负压渗流场分别考虑,然后叠加计算沉降。
The sediment soft soil is widely distributed in Meizi Road,New District,Wuhan City.The vacuum surcharge preloading method was applied to the settlement treatment of foundation.The length of testing area was 300 m and divided into 3 sub areas with 6 cross sections,in which measuring equipments were set up to monitor the deformation on the surface and deep soils.Based on testing results,the settlement of foundation treated by the vacuum surcharge preloading is calculated under the condition of the loading and the vacuum preloading separately and then add up the calculated results together.
