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。
Various distribution models of the coefficient of subgrade reaction can be considered after the two - parameter method is employed . the commonly used " k " method , " m " method , and " c " method can easily be obtained from it . thus , the solutions of the internal force along the studied stabilizing piles have more ordinary representation by the two - parameter method 2 、引入双参数法后,能够考虑土抗力的多种分布模式,常用的m法、 k法、 c法均被涵盖在其中,从而在计算桩的嵌固段内力分布时得到的计算表达式更具有代表性。
