随机波浪荷载下海洋重力式建筑物的位移反应,是工程设计中考虑的一个重要因素,基于对我国某海砂所进行的循环三轴试验成果的分析和研究,文中通过建立起一个考虑了不同初始固结应力状态及不同振次效应的土的综合归一化数学模型,提出了一个分析计算重力式海洋建筑物地基位移反应的拟静力方法。与一般的动力分析方法相比较,这一方法具有简捷方便之特点,文中最后还通过一重力式海洋平台地基位移反应分析的具体算例,表明了文中建议方法的实用性。
Displacement response of marine gravity structures under random wave loads is an important factor considered in engineering design. Based on the analysis and research of the results of cyclic triaxial tests conducted on a certain sea sand in China, Initial consolidation stress state and different vibration effect of the soil of the integrated normalized mathematical model proposed a calculation and calculation of gravity marine buildings displacement reaction quasi-static method. Compared with the general dynamic analysis method, this method is simple and convenient. Finally, a concrete example of the analysis of the displacement response of a gravitational offshore platform is given, which shows the practicability of the proposed method.
