双曲线法在软土地基沉降预测中的适用性研究

Applicability of hyperbolic method in settlement prediction

沉降是软土地基极为重要的工程特性,是岩土工程界一直致力解决的难题。目前用于沉降分析的方法很多,而且各有特色,双曲线法就是其中最常用的方法之一。基于温岭东海塘的道路沉降实测资料,对双曲线法的适用性进行探讨。结果表明,双曲线法预测宜选择沉降曲线后段,预测误差较小,精度较高,可以用于指导工程后期施工实践。

Settlement is a very important engineering property of soft soils. The geotechnical engineering circle has been working hard to solve the problem all the time. Currently, many methods are used for the analysis of the settlement and each has its specific characteristics. The hyperbolic method is one of the most commonly used one. Based on the measured information of the road of East Coast Reclamation in Wenling, the applicability of the hyperbolic method in the settlement prediction is discussed in the paper. The result shows that the latter part of the settlement should be chosen when the hyperbolic method is used, and with small prediction error and high precision. The result can be used to guide the practice of the later construction.
