摘要
对于埋深不大, 在均布径向压力作用下的圆环或圆拱冻结壁, 如果单纯由强度条件计算其厚度时, 往往是薄壁的, 因而必须对其稳定性作验算. 考虑到冻土的应变- 应力的非线性关系, 应用稳定理论的切向模量法对该问题进行了分析, 得到满足稳定条件的冻结壁厚度计算方程.
For the shallow buried circular ring or circular arch freezing wall under radically pressure, it will be thin walled if its thickness is calculated simply by strength conditions, therefore checking computation on its stability must be done .By taking into account the non linear relationship of strain stress of frozen soil and by applying tangential modulus method in the theory of stability, the problem is analyzed, and the equations, which meet the conditions of stability, are derived for the calculation of freezing wall.
