摘要:
为了验证广州市深层隧道排水系统东濠涌试验段工程设计方案的合理性，建立了国内首个深层隧道整体物理模型，对深隧运行过程中的排气、浪涌、消能等关键水力学问题进行了模拟和分析。试验结果表明，折板竖井消能充分，并可兼顾主隧道排气，工程运行期间产生的涌浪和气爆强度较弱，泵站集水池的空间能够满足水泵运行的要求，利用排洪和补水进行水力冲淤具有一定可行性。
Abstract:
In order to verify the rationality of a design scheme for Donghaochong test section of deep tunnel drainage system in Guangzhou City, the first integral physical model of deep tunnel in China was established to simulate and analyze the key hydraulic problems such as exhaustion, surge and energy dissipation during operation of the deep tunnel. Most of the energy could be dissipated by the folded plate shaft, in which exhaustion of the main tunnel could be achieved. The surge and gas explosion intensity generated during the operation of the project was weak. Space of the sump of the pump station could meet the requirement of the pump operation. It was feasible to use flood discharge and water replenishment for hydraulic scouring and silting.
