根据对预压法加固机理的深入研究，作者结合近年工程实践数据对土力学的固结理论公式进行推导，得出一个沉降固结计算的简化公式。该公式将复杂的土体三维固结计算问题进行等效简化，可较准确的计算加固土体各时段的沉降量和最终沉降量。对今后在相近的地质条件下预压法的设计和施工有一定指导意义。%According to the research on the reinforcement mechanism of preloading method, the author who has been analyzing the data of practical project in recent years and been deriving consolidation theory of soil mechanics gets a simpliifed formula. This formula which is simpliifed the main factor of soil three-dimensional consolidation problem can accurately calculate the settlement of reinforced soil in each period and the ifnal settlement. The formula for the future in the similar geological conditions to the design and construction of preloading project is of certain guiding signiifcance.
