本文考虑了影响土石坝施工的几个主要因素(包括气候、汛期拦洪的要求、坝体不同的结构形式、施工进度控制、坝体不同部位的分部填筑上升、以及其他施工约束条件等),建立了土石坝施工全过程的模拟模型,并编制了相应的模拟程序。根据装、运机械的台班费(包括正常施工和停工台班费),以总费用最低为原则,在计算机上模拟,便可在可行域内选择出土石坝施工装、运机械的最优配备方案,给设备的选型配套提供定量的依据。此外,通过对土石坝施工过程的模拟,还可预测土石坝的实际施工进程,对土石坝施工进度可行性进行论证。通过实际工程的计算、分析发现:装、运机械的正确选型配套具有很高的经济效益。
This article considers several main factors that affect the construction of earth-rockfill dam (including climate, flood control requirements in flood season, different structural forms of dam, control of construction progress, different parts of the dam, and other construction constraints, etc. ), A simulation model of the whole process of earth-rock dam construction has been established and a corresponding simulation program has been compiled. According to the loading and unloading machinery costs (including the normal construction and work-stop costs), the total cost of the principle of the minimum, in the computer simulation, we can choose the feasible area of construction equipment installed, the best equipment shipped machinery Program, to provide a quantitative basis for the selection of equipment. In addition, through the simulation of the earth-rock dam construction process, the actual construction progress of the earth-rock dam can also be predicted and the feasibility of the construction progress of the earth-rock dam demonstrated. Through the actual engineering calculation, the analysis found that: loading, transport machinery, the right selection of matching has a high economic efficiency.
