基坑工程重要性定量分级及其应用

现有的国家和地方标准及有关文献中,虽然都涉及了基坑工程重要性等级的划分规定,但有的规定太过单一,有的则过于笼统,不好操作,不利于基坑工程安全及重要性等级的评判和划分。该文提出按计算公式对基坑工程重要性进行定量分级,以便更清晰、更仔细地对基坑工程重要性等级进行评判,从而根据分数和等级,能更容易、更恰当地确定相对应的基坑支护类型和支护方案。

Quantitative Grading of Foundation Pit Engineering Importance and Its Application

The existing national and local standards and relevant literature are involved with the rating system of the foundation pit engineering importance,but some are too unitary,and others are too general to be operated,which go against safety of foundation pit engineering and the evaluation and classification of foundation pit engineering importance.A calculation formula of quantitative grading of foundation pit engineering importance is put forward in this paper,which more clearly and carefully on foundation pit engineering of evaluation.And according to the score of the formula and its results,the corresponding types of foundation pit and supporting plan can be more easily and properly determined.
