复杂地质条件下的城市道路断面设计

由于地形地貌的原因,城市地面道路断面通常情况下均为常规设计。但在局部复杂地形、地质条件下,也会碰到一些常规断面设计方法无法实施的困难,在昆明320国道(眠山-车家壁)段改扩建工程中,电厂大沟鱼塘段断面设计时就碰到了该问题。该文对工程建设中碰到的问题,以及采取的方法进行了总结,以供借鉴。

Sectional design of Urban Road under Complex Geological Condition

The sections of the urban ground roads are all conventionally designed under the common condition because of the landforms and terrain.But some conventional sectional design methods are also hard to implement under the conditions of the partially complex landform and geology.This problem occurs in the sectional design of the Dagou Yutang Section of the power plant when Kunming 320 National Highway (Mianshan to Chejiabi) is under the reconstruction and extension.The article sums up the problems occurring in ...
