IMPROVEMENT ON METHOD OF FOUNDATION SETTLEMENT CALCULATION

摘要

The current coefficient Ψs of correction includes many influencing factors. And the value of this coefficient varies widely. So the current method is improved from one coefficient to four coefficients in this paper. Three new coefficients of correction are considered to decrease composite ratio of coefficient Ψs and three coefficients are put forward to modify calculating result. Foundation stiffness, lateral confinement assumption and soil turbulence are considered to get the value and calculation method of three coefficients. Consequently,this study improves accuracy of calculation result greatly by actual projects.
