摘要
采用伽辽金原理及改进的ＫＢＭ法研究了三参数地基梁热状态下的固有横振．通过实例计算讨论分析了温度升高、地基特征参数对梁热状态下固有频率的影响，得到了一些有价值的结论．表２，参３．
The fixed transverse vibration under the heat stale of the three-parameter foundation wall is studied using Jialiaojin principle and the improved KBM method.The going-up of the temperature is discussed and analysed By the calculation examples, some valuable conclusions are made of original frequency influence under the heat state of the wall of the foundation characteristic parameter.2tabs.,3refs.
