摘    要:通风是大型地下洞室群施工中的重要环节。目前施工通风网络风量的数值解算主要是以简化的Scortt-Hinsley方法为基础。此法的应用具有一定的局限性。本文采用理论上完备的Newton-Raphson方法编制数值解算程序,并以溪洛渡水电站地下洞室群为实例,进行通风模拟计算。将计算结果与用Scortt-Hinsley法编制程序的计算结果进行了对比分析,以期探讨更可靠的风量解算方法,并为整个通风网络系统的调节、优化提供理论依据。

关 键 词:水电工程  通风网络  数值解算  地下洞室群

Abstract:The ventilation is an important part in the construction of large-scale underground tunnel-chamber group.At present,the numerical method to calculate the needed wind quantity of ventilation network is mostly based on the theory of Scorrt-Hinsley.But it is restricted to some extent in application.The theoretic integrated method Newton-Raphson is adapted to compile the numerical calculation program based on FORTRAN in this paper.This program is taken to simulate and compute the needed wind quantity of underground tunnel-chamber group of Xiluodu hydroelectric engineering.The calculating results are contrasted by the results calculated by the program based on the theory of Scorrt-Hinsley in order to get more credible method to compute the wind quantity,and provide the theoretic proof for adjusting and optimizing the ventilation network.
Keywords:hydroelectric engineering  ventilation network  numerical calculation  underground tunnel-chamber group
