摘要
软土地基天然含水量大,压缩性高,承载力低,对建筑物存在极大的不利影响。文中通过珠海某工程软土地基真空预压处理前后十字板剪切试验、土工试验及平板载荷试验数据对比分析,综合评估地基处理效果。涉及到的3种试验方法可以互为验证,也表明当现场不具备条件进行多项试验时,选择其中1~2项试验,得到的结果也具备一定的代表性。研究对类似工程,具有借鉴意义。
The soft soil foundation with great natural water content,high compressibility and low bearing capacity,has great adverse effects on buildings. In the paper,through comparative analysis of cross plate shear test,geotechnical test and plate load test before and after vacuum preloading treatment of soft soil foundation in a project in Zhuhai carries out comprehensive evaluation of the effect of foundation treatment. The three test methods involved in the paper can be verified each other. It also shows that the results from one or two selected tests when the field does not have the conditions to carry out a number of tests,are also representative. The research can be used as reference to similar projects.
