抗浮设防水位问题的探讨

DISCUSSION ON ANTI-FLOATING WATER LEVEL

地下工程的抗浮设防水位对工程的安全性和经济型影响巨大,国家标准对设防水位确定的规定是原则性和指导性的,因而地下工程抗浮设防水位的确定就成为了十分复杂和棘手的问题[1-3]。对国家标准以及部分地方标准在抗浮设防水位确定、地下水抗浮计算原则进行了对比分析,对部分学者的研究成果和观点进行了论述,对上层滞水水位性质、抗浮设防水位的确定方法以及抗浮水头折减等问题进行了探讨。

Anti-floating water level has a tremendous impact on the safety and economy of underground engineering.The provisions of national standards concerning the determination of anti-floating water level are only for guidance,so the determination of anti-floating water level for underground engineering becomes a complex and difficult problem.This paper compares and analyzes the principles in national standards and local standards concerning the determination of anti-floating water level and the calculation of floating force,and discusses the research achievements and perspectives of some scholars as well as the method for determining antifloating water level and the anti-floating head reduction.
