摘要
c和 φ取值是基础工程设计的关键参数 ,由于剪切试验数据的离散性较大 ,常规的处理方法得到的c、φ值 ,难以反映软土的真实值 ,通过试验和大量的资料收集 ,经统计分析 ,得到不同含水量条件下c、φ值的置信区间 ,通过建立剪切强度修正系数的隶属函数 ,构造出c、φ值的线性规划模型 ,优化计算得到的c、φ值 ,不仅安全、可靠 ,而且具有可比性和统一性。克服了目前处理c、φ值的一些缺点 ,方法可行 。
Values of c and φ are the key parameters of ground base in engineering design.Due to rather great scatter character of shearing test data,the values of c and φ getting by usual calculation method are difficult to represent the real of a soft soil.By large numbers of tests and collecting information,the fiducial interval of c and φ are gained by way of statistic analysis of different water contents.Subjection function of correcting coefficient of shear strength is established.Linear programming model of c and φ is constructed.The values of c and φ gained by optimizing calculation are safe and reliable,and have comparability and unity.The method is practicable and applicable to calculate the values of c and φ .Some faults of usual calculation of c and φ values are overcome,by which accurate parameters are provided for engineering design.
