膨胀土特性参数对挡土墙设计的实用性分析

膨胀土因其特有的胀缩特性对构筑物的影响较普通土要大,因此是工程设计中的重点和难点。现有规范对膨胀土的划分标准以及试验参数与挡土墙的联系并不明确,因而影响到挡土墙结构设计的安全性和经济性。该文就此进行了分析并提出建议。

Practicability Analysis of Expanded Soil Characteristic Parameter for Design of Retaining Wall

The expanded soil affects the structures greater than the normal soil because of its special swell-shrink characteristic.Therefore,it is the gist and difficulty in the engineering design.The present criterion is not defined for the dividing standard of expended soil,and the contact of test parameter with the retaining wall so as to affect the safety and economy of the structural design of retaining wall.The article analyzes it and puts forward the suggestion.
