一类简化的竹编水泥沼气池力学模型分析

针对目前在滇南一带开发推广的竹编水泥沼气池，在实地测试和实验室测试研究的基础上，建立一类简化的三次超静定力学模型，并采用力法对赘余力进行严格的数学，力学分析与计算，构造与实际结构接近的理论模型，针对壁厚3,5cm的情形进行数值计算，计算与实测结果基本一致，说明所讨论的模型及力学算法分析是正确的，计算程度是可靠的。

An Analysis on a Kind of Simplified Mechanical Models of Methane Receptacles Constructed of Bamboo- Weaved Concrete

For methane receptacles constructed of bamboo-weaved concrete built in southern Yunnan,P.R.China, the simplified mechanical models of the statically indeterminate structures with three redundant forces resulting from the studies on fields-testing and room-tesing have been established and analyzed in this paper.Some detailed formulae are strictly deduced according to the principles of force method in structural mechanics.Computational programs are designed,giving good results to the approximately theoretical models containing two cases (h=3 cm and 5 cm).All these are very important for the application of methane receptacles constructed of bamboo-weaved concrete.
