摘    要:介绍某造、修船基地软土地基处理工程情况,根据地层条件和使用功能等将地基分为A区和B区:A区采用真空预压法处理;B区采用真空预压和表层拌和换填法处理。按设计要求采用取土试验、十字板剪切试验和静载荷试验进行检测。结果表明:A区的含水量下降了31%左右,B区的含水量下降了39%左右;A区的承载力提高了47-78kPa,B区的承载力提高了160-223kPa,均能满足设计要求。

关 键 词:软土地基 真空预压 表层拌和换填 吹填软土

Abstract:An introduction was given to the soft soil foundation treatment for a ship building base. According to the stratum condition, function, and foundation strength, the base was divided into area A and area B. The vacuum preloading method was adopted in area A, while the vacuum preloading method and surface earth replacing method were adopted in area B. From the soil sampling test, the vane shear test, and the static loading test, it is eoneludod that the moisture content of area A and area B decreases by about 31% and 39%, respectively, while the bearing capacity of area A and area B improves 47-78 kPa and 160- 223 kPa, respectively, The results can meet the requirement of design.
Keywords:soft foundation   vacuum preloading   surface earth replacing   hydraulic fairing of soft soil
