摘要
基于非线性有限元软件ABAQUS,对超深水铺排作业时排体所受水流力进行模拟计算,给出了简化公式。对翻板端软体排所受水平力及垂直力进行比较分析,结果表明在工程实际中可以使用该简化公式对水平力进行估算以及使用软体排重力与浮力之差对垂直力进行估算,此外垂直力引起的横倾角需要在铺排过程中调整压载。
Based on the nonlinear finite element software ABAQUS,we analyze the current force of mattress in ultra-deepwater and give the simplified formula. Comparing the horizontal force and vertical force at the end of the platform trap door,we obtain the results that the horizontal force can be estimated by the simplified formula and the vertical force can be reckoned by the difference between the gravity and buoyancy of mattress in the engineering application.In addition,it is necessary to adjust the ship ballasts in the process of the geotextiles-laying to balance the hell angle caused by the vertical force.
