冻结井筒马头门环形空间水压力研究

Study on water pressure of circular space in horsehead with freezing shaft

以红庆梁马头门穿越冻结壁工程为例,预测计算了冻结管环状空间涌水量,分析了马头门支护结构允许承受的水压力,并通过现场实测和模拟,研究了冻结井筒马头门环形空间水压力,确保了马头门强度满足水压要求。

Taking Hongqingliang horsehead ingate crossing freezing wall engineering as an example, the paper predicts and calculates the annular space water inflow of freezing pipe, analyzes permitted bearing water pressure of horsehead ingate support structure, studies annular space water pressure of the freezing horsehead ingate through in-situ measurement and simulation, so as to guarantee the horsehead ingate strength meeting wa-ter pressure demands.
