| 摘 要： | 复合单元法是一种具有高效建模能力的数值模拟方法，适合用于岩质边坡的动态设计，能够实现模型中结构面、加固措施和开挖面三部分的快速调整。目前复合单元法已经完成对结构面和加固措施的模拟，但还未实现对开挖面及开挖过程的模拟。针对该问题，借鉴复合单元法中结构面模拟的方法，同时结合新的开挖算法，建立了复合单元开挖模型，并使用FORTRAN语言编制了相应的程序。基于边坡开挖算例，与有限元结果的对比，验证新方法的可行性。

| Abstract: | The composite element method(CEM), as one kind of the numerical simulation method, has very high efficiency in modeling. It is suitable for the dynamic design of rock slopes, which can realize quick adjustments of structural planes, reinforcement treatments and excavation surfaces in the model. The algorithms for structural planes and reinforcement treatments have been completed in the CEM. However, the simulation of the excavation surfaces and process has not yet been studied. In this study, the excavation model is set up by using the new algorithm and taking the CEM for simulating excavation surfaces for references. Moreover, the relevant program is coded with FORTRAN. Based on an example of rock slop excavation, the simulated results of the new CEM method are compared with the finite element method, and the validity of the proposed excavation simulation method is proved. |
