| 摘 要： | 以温州发电厂二期煤场工程为例 ,对堆煤自预压法处理大型火电厂的煤场软基工程进行分析研究。首先考虑软粘土的结构性和有限元平面应变分析的等效问题 ,并对其进行数值分析 ,数值预测的结果可较好地控制自预压过程。对大量现场观测资料的分析表明 ,自预压法用于煤场软基的加固是合理有效的。最后得出了一些规律性结论 ,指导同类工程的设计和施工。

| Abstract: | Taking Coalfield project of Wenzhou Power Plant for example, soft foundation improved by self\|preloading of coal is analyzed. An idea is presented that when computing this kind of problem with FEM, two factors, that are the structural properties of soft clays and the equivalent of plane strain analysis, should be taken into consideration. And the calculated results of the numerical methods can control the process of the preloading well. Then on the basis of the investigation data of in\|situ, it indicates that self preloading of the coalfield is reasonable and effective. As a result, conclusions for practical use are obtained, which may guide the design and construction of similar projects. |
