复杂山区高速公路总体设计浅谈

Elementarily Discussion on Overall Design of Expressway in Complicated Mountainous Areas

随着高速公路建设向复杂山区延伸,特殊建设条件带来的高山、高差、高地震烈度和复杂地质情况对总体设计提出了更高的要求。就复杂山区高速公路多方案比选、技术指标灵活运用、防灾抗灾、长大纵坡、生态环保、结构物设置及型式选择、互通选型、造价控制等诸多问题进行了初步探讨。

With the extension of expressway construction into the complicated mountainous areas, the situations of high mountain, altitude difference, strong seismic intensity and complicated geology brought by the special construction conditions are required to put forward the higher standards for the overall design.The article preliminarily discusses the comparison of many expressway schemes in complicated mountainous areas, the flexible application of technological indexes, the prevention of natural adversities, the long and large longitudinal grades, the ecological environment protection, the structure setup and type selection, the selection of interchange type, and the control of construction cost.
