Abstract: 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.
