duration of load
Examples
- Meanwhile , dynamic responses at pile head are investigated . it is sh own that the effects of pile slenderness , bearing stiffness of pile toe and the pile - soil modulus ratio on pile impedance are major whereas the ones of the permeability and the soil reaction coefficient are minor
对影响桩振动特性的主要因素进行了分析，结果表明，长径比、桩土模量比及桩底支承系数对桩的动力响应影响显著，而渗透系数作为饱和土的一个重要参数，由于荷载作用时间问题，对桩的动力响应影响较小。 - When the transportation load is long - term evenly distributed , the influences of each relevant factor , i . e . pipeline depth , diameter , deformation module of foundation , poisson ratio of soil and tyre pressure of vehicles , toward mises stress and vertical displacement of pipelines are discussed . when the transportation load is movable and invariable , the changing rules of mises stress and vertical displacement during the vehicle ' s movement are calculated and analyzed , and effects of vehicle velocity and tyre pressure toward these two mechanical characteristics are discussed . when the transportation load is stable and simple harmonic , the changing rules of mises stress and vertical displacement during the time of load function are calculated and analyzed , and effects of vehicle velocity and tyre pressure toward these two mechanical characteristics are also discussed . in three - dimensional analysis , mises stress and vertical displacement of pipelines under three kinds of transportation loads are calculated , and the analysis and discussion of correlative factors are also made
