downdrag
Examples
- Many survey data refer to mortal down load and sedimentation be produced due to the negative friction in pile foundation . the inequable sedimentation endanger the pile foundation greatly
国内外一些实测资料表明桩基础在使用阶段负摩擦力可能产生非常大的下拉荷载和沉降，尤其产生的不均匀沉降对基础危害最大。 - In this thesis summarize how to avoid and deal with the negative friction in designing and using . researches indicate : ( 1 ) the negative friction in pile will lead to large number of down load in some designs . this friction must be considered in design to avoid the sedimentation and destroy in the building
研究结果表明： ( 1 )在工程设计中，有些情况由于负摩擦力产生的下拉荷载数值相当大，在设计中应充分给予重视，以避免在使用中由于下拉荷载使桩的轴向荷载增加引起桩的沉降或不均匀沉降，而导致建筑物的破坏。 - This thesis put forward a systemic method to settle the negative friction in project design . it includes when the negative friction must be consider , the zero position decided , count the down load , the negative friction group pile , the infection on end - bearing and sedimentation and stability , how to deal with in design to avoid the negative friction and how to solve when the negative friction produced
本文提出了在工程设计中如何处理桩基负摩擦力的方法，包括什么情况下考虑负摩擦力、负摩擦力中性点位置的确定、桩基下拉荷载的计算、负摩擦力的群桩效应、负摩擦力对桩基竖向承载力和沉降的影响、设计施工中如何避免出现负摩擦力以及对已经出现的负摩擦力如何根治。
