摘要
裸露型岩溶地区强烈发育的岩溶地质现象给公路路基施工造成困难,处理不当将产生种种严重病害而影响到公路路基结构的正常使用。通过对病害成因分析,认为形态极不规则的岩溶岩体和多变的岩溶水是造成病害的根本原因,提出了以尺度划分原则选取病害处理措施的方法,总结出了9种病害防治措施。
<Abstrcat> In the bare karst zone, the strong karstification makes many problems to subgrade construction of highway. If the necessary treatments were not taken, severe harm to highway subgrade structure would be created and the normal function would be affected. In the paper, the irregularly rock mass and the changeable karst water are considered as the real causes for the subgrade diseases, such as settlement, collapse etc. The method being selected on the principle of scale-division is put forward, and nine kinds of the prevention and treatment techniques for subgrade diseases are discussed in detail.
