| 摘 要： | 针对某海域的综合治理工程,选取一吹填强夯处理试验区,室内试验表明吹填强夯的压实度满足大于90%的设计要求。在现场进行了不同的原位力学性能试验,平板载荷试验、重型动力触探试验以及原位旁压试验,试验结果表明吹填强夯的地基承载力均大于100 kPa的设计要求,450 kN的平板载荷试验的最大沉降16.53 mm,最小沉降12.88 mm。深层和浅层重型动力触探的试验结果均表明强夯加固效果明显。不同深度处的旁压试验结果表明地基承载力标准值最大可达347 kPa,在1.1 m处地基承载力标准值最小为209 kPa。因此,从现场试验结果可以看出,吹填强夯联合处理海域软土是一种较好的方法。

| Abstract: | A field test area was selected for a marine soft soil treatment.After the treatment of hydraulic reclamation and dynamic consolidation,a series of lab tests are conducted,these tests results show that the degree of compaction of foundation improved by it is satisfied with the design requirement which the degree of compaction is more than 90%.In addition,lots of in |situ mechanical tests are used to examine the effects of it,such as plate loading test,heavy dynamic penetration test and pressuremeter test.The... |
