摘要
软土土性指标是软基处理设计的关键参数,其值具有很强的地域性和显著的不确定性。本文基于乐清湾港区疏港公路沿线区域350件原状淤泥质软土的土工测试数据,系统地统计分析了该地区滨海淤泥的基本物理力学指标;通过正态分布检验,对各指标的概率分布模型进行了统计分析;通过线性回归分析,提出了滨海淤泥主要物理力学指标之间的相互关系,初步揭示了乐清湾滨海地区的淤泥的工程特性,以期对以后工程有借鉴指导意义。
In the design of soft soil foundation treatment, the soft clay indices are the key parameter, which have the strong geographical feature and significant uncertainty. Based on the experimental clata from the 350 natural oozes in the area along the port highway in Yueqing bay, the basic physical and mechanical indices of the ooze in the area are systematically analyzed, and the probable distribution models of the indices are analyzed with statistic methods on the basis of the normal distribution test. Based on linear regression analysis, the interrelation of the indexes is proposed, and the engineering properties of the littoral deep ooze in Yueqing bay are preliminarily revealed. The study results could give some reference for future projects.
