Based on shear stress - strain relation of soft soil , an approximate solution to the coefficient of subgrade reaction in elastic stage is proposed 在对软土流变研究的基础上,采用抗剪强度折减的方法在基坑工程中考虑流变的影响。
Moreover , the coefficients of subgrade reaction are often determined by empirical analysis , which influences the security and economy of foundation engineering 这对围护结构变形、内力预测结果的影响很大,直接影响了围护结构方案的安全性和经济性。
The analytical and numerical solutions of the established mathematical model have been achieved . in the whole paper , two - parameter method is employed to calculate the coefficient of subgrade reaction or subgrade modulus 本文将双参数法引入到土抗力模数或地基系数的计算中,并贯穿到整个结构计算中。
