解釋
正割公式-
The reliability of secant modulus method is validated in which final consolidation settlement is computed. the experience formula of coefficient of permeability ( k, 0 ) and pore ratio ( e ) is presented and the experience expression of coefficient of permeability ( k10 ) and strain ( ) is offered too. lt is important to modity the acquiring method of coefficient of consolidation, because the method embodies that strain and pressure of consolidation effect on coefficient of consolidation
本文首先驗證了用割線模量法計算軟土地基最終固結沉降的可靠性;其次得到了滲透參數k _ ( 10 )和孔隙比e的經驗關系,並且更進一步給出了滲透系數k _ ( 10 )和應變之間的經驗公式,更重要的是對求取固結系數的方法給予了改進,該方法反映了固結系數隨應變和應固結壓力的變化規律。
