1、樁基豎向抗壓承載力計(jì)算 樁身周長:u=πd=3.14×0.8=2.51m 樁端面積:Ap=πd2/4=3.14×0.82/4=0.5m2 承載力計(jì)算深度:min(b/2,5)=min(5/2,5)=2.5m fak=(2.5×240)/2.5=600/2.5=240kPa 承臺底凈面積:Ac=(bl-nAp)/n=(5×5-4×0.5)/4=5.75m2 除以4是何意? 復(fù)合樁基豎向承載力特征值: Ra=ψu(yù)Σqsia?li+qpa?Ap+ηcfakAc=0.8×2.51×(2.4×55+5.7×30+4.2×50+4.3×70)+2000×0.5+0.1×240×5.75= 2779.89kN應(yīng)該為 (2772.5)計(jì)算有誤問題補(bǔ)充:幫忙解答:承臺底凈面積:Ac=(bl-nAp)/n=(5×5-4×0.5)/4=5.75m2 除以4是何意?2779.89kN應(yīng)該為 (2772.5)計(jì)算有誤...閱讀全文
