利用波动方程分析程序模拟某超大跨海工程大直径钢管桩的打桩过程,并根据实际桩-土-锤系统参数进行可打性分析,确定桩-土-锤系统性能及桩的运动和受力状况。波动方程分析可采用不同的打桩锤模拟计算,得到锤击数、承载力、桩身拉应力和压应力结果。通过比较,选择最佳的打桩锤并制定合理的沉桩标准,估计总的打入时间。
Using the wave equation analysis program to simulate the piling process of a large-diameter steel pipe pile of a large offshore project, the feasibility of the pile-soil-hammer system and the movement and acceptance of the pile are determined according to the actual parameters of the pile-soil-hammer system Force situation. Wave equation analysis can be calculated using different pile hammer simulation, get hammer number, bearing capacity, pile body tensile stress and compressive stress results. By comparison, the best piling hammer is selected and a reasonable pile sinking standard is established to estimate the total launch time.
