针对某港口工程大型贮煤筒仓,首先考虑在筒仓荷载作用下的天然地基土的沉降量,判别筒仓是否需要设置桩基础;然后分别采用等效置换土体法和考虑桩土相互作用的有限单元法,分析了贮煤筒仓的基础土体沉降变形规律、桩的内力与变形。从计算结果可知后两种方法计算的土体沉降量大体一致;考虑桩土相互作用的方法,更加与实际情况接近。
針對某港口工程大型貯煤筒倉,首先攷慮在筒倉荷載作用下的天然地基土的沉降量,判彆筒倉是否需要設置樁基礎;然後分彆採用等效置換土體法和攷慮樁土相互作用的有限單元法,分析瞭貯煤筒倉的基礎土體沉降變形規律、樁的內力與變形。從計算結果可知後兩種方法計算的土體沉降量大體一緻;攷慮樁土相互作用的方法,更加與實際情況接近。

In order to design the large-sized coal silo of harbor engineering, it is important to consider the settlement of natural foundation soil under silo load and determine whether the pile foundation has to be set. In addition, the settlement deformation rule of coal silo foundation soil, internal force and deformation of piles have been analyzed by using finite element method relying on pile-soil interaction and the equivalent soil-replacing method respectively. The equivalent soil settlement has been gotten by the above two methods. However, pile-soil interaction method reflects the real settlement better.
