1987～1991 年,作者对高压混凝土堵头的设计、施工及运行进行了研究。搜集了30多个堵头的详细资料,并进行了分析。堵头的静水压力最高接近1 000m 。混凝土堵头的长度为静水压的2～5% ,钢板衬砌可以短至静水压的0.4% 。自1980年以来,技术的发展主要体现在堵头的透水性降低 From 1987 to 1991, the author studied the design, construction and operation of high-pressure concrete plug. Collect more than 30 plug details, and conducted an analysis. Plug the hydrostatic pressure up to nearly 1000m. The length of the concrete plug is 2 ~ 5% of the hydrostatic pressure and the lining of the steel plate can be as short as 0.4% of the hydrostatic pressure. Since 1980, the development of technology is mainly reflected in the reduction of water permeability of the plug
