The soil profile may be arbitrarily layered with a rigid stratum at a certain depth . by contrast with the practically measured data in large - scale cast - in - place pile prototypetest , it can be seen that the method proposed in this paper is simple and comparativelyaccurate in calculating the pile settlement under working load 樁周土可以任意分層,并且距剛性基底可以是有限深的,通過與大型灌注樁原型試驗(yàn)實(shí)測數(shù)據(jù)對比,說明本文方法計(jì)算工作荷載下單樁的沉降是簡單而又比較準(zhǔn)確的。
