基于ArcGIS的山东省公路岩土区划研究

摘要

The determination of technical standards and the scale of investment on highway con-struction projects are greatly influenced by the diversity of geotechnical conditions in the region.The ex-isting highway natural zoning,of which indicators are almost related to climate,are lack of practicality and pertinence in the actual road construction,therefore,it is very necessary to do researches on the highway geotechnical zoning provincially.By sufficiently considering the highway network planning target and the need of economic development of Shandong province,this paper determines the indicator system of highway geotechnical zoning of Shandong Province,dividing Shandong Province in accordance with its geotechnical conditions by using the ArcGIS technology platform.“The 1:2 000 000 highway geotechni-cal zoning map of Shandong Province”was completed and the geotechnical engineering characteristics of each partition were described in the end.The results can be used as scientific basis for taking advantages and avoiding disadvantages,as well as the reasonable and efficient use of materials in the process of plan-ning,designing,building,operating and conserving of highway engineering projects in Shandong Prov-ince.It also provides the completion of highway comprehensive natural zoning map of Shandong Province with basic data,offering important reference value to other provinces and cities in China,in where re-searches on highway natural zoning are launched.%区域内岩土条件的差异性影响着公路建设项目技术标准的确定和投资规模，现有的公路自然区划多以气候为指标划分，在实际公路建设中的实用性和针对性不强，因此研究省级公路岩土区划显得十分必要。在充分考虑山东省公路网规划目标及经济发展需要的基础上，确定了山东省公路岩土区划研究框架及指标体系，利用 ArcGIS 技术平台，将山东省按其岩土条件进行区划分区，完成了“山东省1∶200万 km岩土区划图”并对各个分区的岩土工程特性进行了说明。研究成果可为山东省公路工程的规划设计、建设施工及运营养护等的趋利避害及材料的合理有效使用提供科学依据，为山东省公路综合自然区划图的编制提供基础资料，对我国其他省、区、市开展公路自然区划的相关研究具有重要参考价值。
