Thirdly , a calculation formula of distortion settlement is established by considering soil structure damage and plastic drain board restraining displacement of soft foundation . starting with discussing the main factors affecting settlement of consolidated foundation , a reasonable method to modify the calculated settlement of soft foundation by layer - wise summation method is presented here . with calculable coefficients of volume deformation , lateral displacement and structure damage to modify the settlement will be closed to measurer settlement ( )在土體損傷理論的基礎(chǔ)上建立了考慮結(jié)構(gòu)損傷、排水板加筋作用的瞬時沉降計算公式,分析了影響土體沉降的主要因素,提出了對按單向分層總和法計算的固結(jié)沉降量進(jìn)行體積應(yīng)變、側(cè)向位移、土體結(jié)構(gòu)損傷三項修正的方法,以上述三個修正系數(shù)取代原來單一的綜合經(jīng)驗系數(shù),使沉降計算值與實(shí)測值更接近。
