New type of steel bifurcation with inner crescent rib 内加强月牙肋钢岔管新型结构
2.
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。
