冻结法施工立井井筒井壁结构设计研究

Research on structural design for shaft wall structure with freezing method

简述了冻结法施工的井筒井壁结构形式,研究了钢筋混凝土双层井壁厚度的计算方法,并以内蒙古某矿井为工程背景,对考虑混凝土强度提高系数前、后的计算结果进行了对比分析,以减薄井壁厚度,从而减少矿井投资。

The paper indicates the shaft wall structure of the freezing method,researches the calculation methods for the double-layer shaft wall thickness of the reinforced concrete,taking a mine of Inner Mongolia as an example,and undertakes the comparison and analysis of the calculation results before and after the improvement of coefficients of the concrete strength,so as to reduce the shaft thickness and coal mine investment.
