目前,国内外分析、评价砂土液化的方法很多,但是不管用那一种方法都得不出准确满意答案,因此对砂上液化的评价难度较大,在此情况下,原文作者提出了以极限平衡理论作为评价饱和破土在往返荷载下开始破坏的准则,拟定了测试、分析方法。这不但对土工研究是很有意义的,而且,我们通过十几项工程的实际应用,也证实在某些情况下确具有很大的实用价值。但我们认为还有以下几个问题值得商榷。
At present, there are many methods for analyzing and evaluating sand liquefaction at home and abroad, but no matter which method is used, accurate and satisfactory answers cannot be obtained. Therefore, it is difficult to evaluate liquefaction on sand. Under this circumstance, the original author puts forward the limit. The theory of balance is used as a criterion for evaluating the damage of saturated ground under the reciprocating load and a test and analysis method is developed. This is not only significant for the geotechnical research, but also through the practical application of more than a dozen projects, we have also confirmed that in some cases it has a great practical value. However, we believe that the following issues are still worth discussing.
