Research On The Application Of The Stress Remolding Method In The Slope Engineering

Our country have many construction engineering all over the nature now, andin order to satisfy our needs ,we always form many slopes, how to analysis theseslope's safety coefficient and how to father the dangerous slope by reasonable andeconomical method is a difficult problem which puzzle the engineer and scientistfor many years. The method used widely now in the slope engineering is usinggiven slip face to calculate the slope safety coefficient which is based on limitedequilibrium method, but this method have big bug in the theory. So when we usethis method in the engineering practice, we almost meet the example that thecalculating result is not equal to the practice. The new method of remolding stressis systemic introduced how to used in the slope engineering in this article. How toanalysis the slope safety coefficient and make the slope to reach the appointedsafety coefficient after fathered. The method of stress remolding can solve thisproblem beautifully. To calculate the safety coefficient according to the state ofstress of soil in the slope, and load the remolding stress to make the slope reach theappointed safety coefficient. And the author use large finite element softwareANSYS to analysis the soil's state of stress before and after the remolding to provethe method of remolding stress is economic and reasonable in fathering dangerousslope. And we can accept very good effect if we use expanding anchor to carry outremolding stress. We can also applied other measure to carry out as anti-slide pipe,retaining wall, anchor etc. Using method of remolding stress is a complete methodto analysis and father slope and is divorced from limited equilibrium methodcompletely ,and is feasible and reasonable however in the practice or theory, andthis new method will bring great sense.
