摘　　要：文章以某输电线路工程为例,通过现场调查,根据施工桩基开挖所见,阐述了不同溶沟、溶槽式喀斯特的地质特征,并据此探讨溶沟、溶槽地质条件下的勘察注意要点。通过分析施工开挖所见溶沟、溶槽型溶洞的形态、大小、延伸方向,表明针对不同类型的溶洞,可采用全充填或局部充填的处理方式,每个溶洞都有其特异性,应进行个性化分析处理。Taking an electricity transmission line project as an example,through field investigation,according to the view in pile foundation excavation construction,this paper expounds the geological characteristics of different kinds of karren karst,and discusses the key points of investigation under the geological conditions of karren karst.By analyzing the shape,size and extension direction of the karren karst cave seen in the excavation construction,it is shown that for different types of karst caves,the treatment methods of full filling or partial filling can be used.Each karst cave has its own specificity and should be analyzed and processed individually.
