摘要
深圳地区滨海软土具有含水量大、压缩性高、强度低、承载力低以及结构性强等工程特性。通过对固结沉降理论分析,提出软土固结沉降计算应注意参数选取、超载量的确定、差异沉降等问题。针对深圳地区大面积软土工程具体条件,采用堆载预压法、抛石挤淤法以及复合地基法等技术措施进行软土加固收到良好的效果。
The marine soft soils in coastal area of Shenzhen region were generally exhibited characteristics of high water content, high compressibility, low strength, low bearing capacity and strong structural characteristics. The theory of consolidation and the calculation of settlement were analysed preliminarily. Some critical problems such as soil parameters, overloading and differential settlement, requiring attention during the theoretical calculations, were then presented. Several technical measures such as preloading, composite foundation and riprap and displacement methods can be adopted for reinforcing the marine soft soil under corresponding special engineering conditions. These measures have been testified to be very effective.
