【提要】 將交叉條形基礎視為由若干帶矩形側(cè)翼的縱向條形基礎組成，忽略次要影響因素進行分析，得到基于文克勒地基模型的豎向荷載簡化分配公式，進而提出“逐次逼近法”及其計算公式。經(jīng)算例驗證，方法切實可行，結(jié)果正確合理，經(jīng)系數(shù)化處理的計算公式簡便實用，可供設計采用。
【關鍵詞】 交叉條形基礎 基底尺寸 逐次逼近法
Simplified Method to Calculate Base Area of Gridmat Foundation/Wu Nengsen (Traffic of College, Fujian Agricultureforestry University, Fuzhou 350002, China)
Abstract:The constitution that a gridmat foundation is composed of several lengthwise s
trip foundations with a few flank wings is presented. Based on the Winkler's ground model, a simplified formula for allocating vertical loads is derived, in which some minor factors are neglected. Then the progressive approach method and its formulas are brought out.Through an engineering example,it is testified that the method and the formulas are feasible and convenient for engineering design.
Keywords:gridmat foundation; sizes of foundation base; progressive approach method
