A.對(duì)無相鄰荷載影響,基礎(chǔ)寬度為1~30m時(shí),變形計(jì)算深度可根據(jù)基礎(chǔ)寬度按簡(jiǎn)化公式zn=b(2.5-0.41nB.計(jì)算求得
B.對(duì)獨(dú)立基礎(chǔ)變形計(jì)算深度自基礎(chǔ)底面算起不應(yīng)小于1.5倍基礎(chǔ)寬度且不宜小于5m
C.變形計(jì)算深度應(yīng)滿足計(jì)算深度向上取△z(按規(guī)范取值)厚的土層計(jì)算變形值小于地基計(jì)算變形量的2.5%
D.當(dāng)計(jì)算深度范圍內(nèi)存在基巖或厚層堅(jiān)硬土層時(shí),計(jì)算深度可取至該層土表面
