深井高压大水淹井治理的封水层厚度理论分析与计算

THEORICAL ANALYSIS AND CALCULATION OF WATER ISOLATION LAYER THICKNESS FOR CONTROLLING DEEP SHAFT HIGH PRESSURE WATER FLOOD SUBMERGENCE

在井筒淹井治理工程中 ,抛碴注浆封底所采用的封水层设计厚度 ,多根据前苏联的有关理论公式确定 ,实际应用中可针对性不强。本文从封水层受力分析入手 ,对封水层厚度进行了理论计算 。

To design the thickness of water isolation layer for slag grouting floor sealing in shaft submerging control engineering,most determinations are produced in accordance with former SU′s theorical fomulas.They are not suitable for practical applications.The author theorically calculates the thickness of water isolation layer according to the pressure of water isolation layer to provide reliable bases for the project engineering.
