| 摘 要： | 研究场区为"覆盖型"岩溶区。为提供公路选线、桥梁设计施工战略决策依据,为今后类似勘察区积累经验,在补勘资料基础上,对场区岩溶分布、形态、制约因素及其发展趋势作了初步分析,重点提出岩性、构造、地貌及彼此间最佳组合状态是岩溶发育的关键。结论是场区岩溶的发展已处于衰亡期。

| Abstract: | The construction site belongs to an overlaid-type karst area.Based on the supplementary exploration information,the authors conducted some analyses on the karst distribution,shape,restricted factors and its trend,with focuses on lithology,structure and landform as well as their optimal combination state,for they were fatal to the development of karst.It is concluded that the karst development at the site went into its contabescence epoch. |
