高桩码头桩基沉降研究

Analysis of Pile Foundation Settlement of Piled Berth Structure

高桩码头桩基沉降会对上部结构内力产生一定的影响,但是通常情况下并不进行计算。为了确定码头桩基沉降量,本文结合工程实例,用了理论计算和数值模拟两种方法对桩基沉降进行了计算。结果表明,高桩码头整体沉降大概为几十毫米,不均匀沉降为几毫米。通过对两种计算方法进行对比得出,理论计算更加贴近实际情况,可以作为一种桩基沉降计算的有效方法。

The pile foundation settlement may cause a significant impact on the internal force of the upper structure of piled berth structure,which is not commonly included in the calculation.In order to determine the amount of pile foundation settlement,the theoretical calculation and the numerical simulation are applied in the settlement calculation respectively based on a specific project.The results show that the whole structural settlement is approx.dozens of millimeters and the differential settlement is about several millimeters.The comparative analysis of the two methods indicates that the theoretical calculation result closely approximates to the real-measured data,thus the theoretical calculation can serve as an effective method for calculating the pile foundation settlement.
