在采矿或地下工程中,遇有流沙层时,常采用冻结法施工。这种利用冻土围幕的环效应来抵制水土压力的方法取得了不少经验,但也有因冻结场温度应力而导致钢筋混凝土井壁产生大量环向裂缝的。不少文章以弹性理论厚壁筒公式对温度应力进行计算,得出了井壁有环向开裂的结论。而笔者在同样的温度条件下,用自由圆筒公式计算,尽管计入了冻土对井壁的弹性约束,也依然没有得出环向开裂的结论。故本文在论述了用弹性理论方法考虑 In mining or underground engineering, the case of quicksand, often using the freezing method of construction. This method of utilizing the ring effect of permafrost to resist water and earth pressure has gained a lot of experience. However, there are also lots of circumferential cracks in the sidewall of reinforced concrete due to the temperature stress in the frozen field. Many articles calculate the temperature stress based on the elastic thick shell formula, and draw the conclusion that there is circumferential cracking in the borehole wall. And the author in the same temperature conditions, calculated using the free cylinder formula, despite the inclusion of frozen soil wall constraints, but also still did not come to the conclusion of circumferential cracking. Therefore, this article discusses the use of elastic theory method to consider
