采用混合法建立了桩-土-筏系统非线性简化分析模型,编制了桩-土-筏非线性共同作用分析程序,给出了程序关键技术处理。该方法合理利用了荷载传递法、弹性理论法、有限单元法多种方法的优点,既能反映非线性的工作性状,又显著的降低了内存的需求,实现精确性与高效性的较好结合,使实际工程问题的分析成为可能。
The nonlinear simplified analysis model of pile-soil-sluice system was established by the hybrid method. The nonlinear combined action analysis of pile-soil and concrete was programmed, and the key technical processing of the program was given. This method makes good use of the advantages of load transfer method, elasticity theory method, and finite element method. It can not only reflect the non-linear working properties, but also significantly reduce the memory requirements, and achieve a better combination of precision and high efficiency. This makes it possible to analyze actual engineering problems.
