摘要：

【背景】钻孔包含丰富的岩溶空间信息，但数据离散性大，难以直接用于刻画岩溶空间形态。【方法】以铜山源高架桥为例，全面收集各阶段钻孔数据，选择岩溶发育高程、高度、概率三类共6个指标，采用数理统计及指标散点图的单指标和多指标分析，探索岩溶形态多指标最优组合方法，获得岩溶形态统计规律及其分布特征。【结果】研究表明：（1）单一指标反映了岩溶形态不同方面的局部特征；（2）按溶洞底板高程从低到高顺序绘制的多指标散点图具有显著规律性，能确定浅部溶蚀基准面，进一步将钻孔岩溶划分为深部岩溶DD类和浅部岩溶SD类；（3）工程地质平面图中不同类型的岩溶具有明显分区特征，剖面图中具有不同的岩溶形态，工程地质条件差异大；（4）根据岩溶类型划分，使得勘察设计和施工更有针对性。【结论】岩溶多指标散点图方法，能有效解决工程建设中岩溶形态判断的困难，且能利用长期积累的大量钻孔数据，为定量分析区域岩溶发育情况提供基础。

Abstract:

[Context] Boreholes contain abundant karst spatial information, but the data is highly discrete and difficult to describe directly the spatial morphology of karst. [Methods] In this paper, the Tongshanyuan viaduct is taken as an example. The drilling data of each stage is comprehensively collected; six indicators of karst development elevation, height, and probability are selected; and mathematical statistics and index scatter diagram are used to conduct single and multiple indicator analysis, to explore the optimal combination method of multiple indicators of karst morphology, and to obtain the statistical law and distribution characteristics of karst morphology. [Results] The study shows that: (1) a single index reflects the local characteristics of different aspects of karst morphology. (2) The multi-index scatter map drawn according to the order of karst cave floor elevation from low to high has significant regularity, which could determine the shallow karst base level. Through the relationship between the borehole karst cave floor elevation and the shallow karst base level, the borehole karst can be divided into deep karst DD class and shallow karst SD class. (3) Different types of karst in the engineering geological plan has obvious zoning characteristics, and different karst forms in the profile map has great differences in engineering geological conditions. (4) According to the classification of karst types, the survey, design, and construction are more targeted. [Conclusion] The karst multi-index scatter map method could effectively solve the difficulty of karst morphology judgment in engineering construction and could use a large number of long-term accumulated borehole data to provide a basis for quantitative analysis of regional karst development.
