摘要西龙抽水蓄能电站岔管规模远超过国内已建工程，为降低制作、安装难度，考虑岔管与围岩联合受力设计。
This test provides the important bases for determining the design parameters and studying the combined bearing law of the y - pipe and surrounding rock modeling under actual bearing conditions and the construction technology of y - pipe tests of site structural model
在大量结构分析基础上，通过现场结构模型试验对埋藏式岔管实际受力状态和施工工艺的模拟，为设计参数取值、岔管与围岩联合受力规律研究，提供重要的科学依据。
The experimental method of the model test with 1 : 6 scale based on the work mechanism of bearing of steel y - pipe strengthened inside with crescent rib in combination with surrounding rock mass simulated by composite materials is adopted and the regularity of their participant capacity to bear inner water pressure is analyzed in this paper
摘要本文结合实际工程采用几何比尺为1 : 6的物理模型试验方法，用不同材料分层组合模拟围岩，对水电站内加强月牙肋钢岔管与围岩联合承载的工作机理、围岩分担内水压力的规律进行分析。
