  1. The preferences are analyzed, pipe ’ s parameters such as depth, thickness, pipe diameter, and mechanical property of material ; soil parameters such as soil types, internal friction angle, pipe - soil interaction ; fault ’ s parameters such as fault types, fault throw, fault drop, fault - pipe angle, mechanical property of material ; load types such as gravity force, linear displacement load, seismic load and seismic wave. some conclusions are drawn from the calculating results : when buried pipes cross fault, pipe ’ s embedded depth should be shallow, and big pipe diameter and thick wall should be selected. avoid the site where fault moves severe, and select suitable pipe - fault angle

    在有限元三維模型建立中考慮的因素有:管道自身參數如管道埋置深度、管厚度、管徑、管道材料等;巖土材料參數如土體類型、巖土的內、管土相互作用等;斷層考慮有斷層類型,斷層斷距,斷層錯動距離,斷層與管道的交,斷層材料的考慮等;荷載分別考慮靜荷載,動荷載,其中動荷載包括線性位移加載、地震力加載和地震波加載等。
  2. Result of numerical simulation shows that the grads of continuous phase " s velocities decreases with the presence of microbubble of which the diameter is 100 / / w, the profiles of air volume fraction in the boundary layers is similar to triangle or echelon, affected by interaction among the particle, there is a saturated air fraction, within the scope of saturated air fraction, increasing the air injection ratio can accrete the friction reduction ratio, under the condition of same air injection ratio, the free - steam velocity is larger, the effect of friction reduction is worse

    計算結果表明,直徑為100 m的微氣泡能減小近面連續相的速度梯度;微氣泡在邊界層中的濃度分佈近似為三形或梯形分佈;受粒子間相互作用的影響,存在一飽和濃度;減阻率隨噴氣量的增大而增大,直至飽和噴氣量,此後,增大噴氣量,阻力變化不大;相同噴氣量下,來流速度越大,減阻率越低。
