摘　　要：曹妃甸海事码头为3 000吨级重力式空心方块码头,地基土层主要是粉砂层和粉质黏土层,工程地质性质较好。利用分层总和法对码头沉降进行计算,并采用有限差分法进行数值模拟计算,通过合理选择关键参数(单向压缩经验系数和弹性模量)上述两种方法得出的计算结果与观测数据基本吻合,从而验证了两种计算方法在类似地质条件下的适用性。The 3 000 DWT gravity wharf is a hollow concrete block quay wall built on the strata of silty sand and silty clay,which has favorable engineering geologic features. This article calculates the wharfs settlement by the layer wise summation method, and makes numerical simulation by finite difference method. Selecting critical parameters（ one dimension compression empirical coefficient and elastic modulus） reasonably, the calculation results given by the above-mentioned method are identical to the measured data,which proves that the calculation methods are appropriate to similar geologic conditions.
