深井冻结壁变形计算的理论分析

A theoretic analysis on deformation of deep shaft frozen walls

本文根据国家七·五攻关项目(75—12—04—04)“冻结壁强度及其参数研究”的实验结果及现场实际情况,采用理论分析法,推得冻结壁的变形公式。利用公式计算,所得结果与其它现有公式计算结果相比较,更接近试验值,表明更为合理,可作为深井冻结壁设计的又一理论依据。

With the method of theoretic analysis used,a formula of frozon walls deformation is dedused here according to site practice and the experimental results of the Third-five-year National Scientific Research Project-study on strength and its factors of frozen walls. The calculation resultsof this new formula are close to the test' s.showing that it is more reasonable than other present formulae and can be used as another theoretic basis for the design of deep shaft frozen walls.
