摘　　要：NL法是港口工程中常用的桩基水平承载力的计算方法,由于计算公式复杂,规范提供了相似原理进行理论计算,并提供了标准桩的计算表格,由于当时计算条件有限,标准桩的计算精度不高,存在一定误差。文章通过编写的有限元程序对标准桩的计算数据进行了修正,使得应用NL法理论计算时精度更高。NL Method is a widely used method for pile level capacity in harbor engineering. Since the formula is very complex, codes provide a similar principle for theoretical calculation and forms of standard piles as well. Because of the limited condition, the accuracy of the standard piles provided by the code is not high and there are still some errors in it. This paper amends the data of these standard piles by means of compiling finite element programs so as to further improve the NL Method.

关 键 词：NL法 水平承载力 相似原理
