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。
The anti-floating waterproofing level of underground project has a great impact on the safety and economy of the project. The national standards for determining the waterproofing level are both principled and guiding. Therefore, the determination of anti-floating waterproofing level of underground works becomes very complicated and difficult The problem [1-3]. The national standards and some local standards in the anti-floating waterproof level to determine the principle of groundwater anti-floating calculated comparative analysis of some scholars of the research results and opinions were discussed on the nature of stagnant water level, anti-floating waterproofing method to determine the location As well as anti-floating head reduction and other issues were discussed.
