骤加荷载 meaning in English

suddenly applied load
suddenly-applied load

Firstly , by the method of laplace transform , one dimensional consolidation of one - layer gibson soils under time - depend loading is studied and the analytical solutions in frequency domain are obtained . on the basis of the solutions obtained and the computation through programming , the influence of some parameters and loading conditions on the consolidation behavior under trapezoidal , triangular and rectangular cyclic loading , is investigated . secondly , one - dimensional consolidation of one - layered gibson soils with semi - pervious boundaries is studied in this paper , and according to numerical examples , some characters of consolidation such as the effective stress and settlement in the soils under arbitrary loading are found
首先运用了laplase变换获得了单层gibson地基(压缩模量随深度线性增加的地基)在任意荷载下频域内的一维固结解析解，通过laplace逆变换，基于以上解答用数值方法编制程序对单层地基在常见荷载(骤加荷载、缓加荷载、矩形波载、三角形波载)作用下的一维固结性状进行了讨论，并与传统的太沙基理论进行了比较。
