复杂条件下山区河流便民交通码头平面布置研究OA

In response to the troubles involving in the construction of convenient transport marinas along the mountain rivers,such as steep terrain,significant water head and limited layout conditions,by studying a convenient transport marina along a mountain river in Yunnan Province,four general layout plans were proposed subject to the project boundary conditions,including a vertical shoreline layout with stepped ramp road(freight transport and passenger traffic);a combination of L-shaped and S-shaped ramp roads;a combination of broken-line vehicle access to river and a L-shaped passenger transport stepped ramp road;a combination of a broken-line vehicle access to river,a L-shaped stepped ramp road,and a U-shaped ramp road.A detailed comparative analysis of the above technical solutions revealed a comprehensive berth plan that combining the broken-line vehicle access to river,L-shaped stepped ramp road and U-shaped ramp road together.End-step platforms,multi-section broken-line ramp road and the functional berths were integrated to effectively shorten the length of ramp road,reduced the amount of earthwork being excavated and filled,and lowered the project investment.At same time,The plan met the requirements for the ship berthing stability and freight transport efficiency under different water levels,balanced both economy and feasibility.The results provided technical reference for similar projects.
