摘要
为实现地质工作有效服务城市建设与规划,通过调查和研究对牡丹江市市区地貌类型重新进行了划分和厘定;综合对比分析钻孔和测试数据,按“时代-成因-岩性”对市区50 m深度范围岩土体进行了工程地质层组划分,为牡丹江市工程地质勘察工作提供了统一的分层参照准则;最后,依据地貌成因、形态及岩土工程地质特征,对市区范围进行了工程地质分区。研究结果表明:1)牡丹江市地貌按成因类型可划分为5类,按形态类型可划分为7类;2)市区50 m深度范围内岩土体可划分为11个主层,30个亚层;3)市区范围内可划分出4个工程地质区和5个松散土体工程地质亚区。
In order to effectively serve urban construction and planning with geological work,this paper redefines the division of the geomorphic types of Mudanjiang city through investigation and research.Comprehensive comparative analysis of the drilling and test data,the engineering geological strata groups of rock and soil within 50 m depth in the urban area are divided according to"age-origin-feature",which provides a unified layered reference criterion for engineering geological investigation in the city.At last,the engineering geological division is carried out according to the geomorphic origin,morphology and geotechnical engineering geological characteristics.The results show that:1)The landform of Mudanjiang city can be divided into 5 types according to the genetic type and 7 types according to the morphological type;2)the rock and soil can be divided into 12 main layers and 31 sub layers within the depth of 50 m in the urban area;3)the urban area can be divided into 4 engineering geological areas and 5 loose soil engineering geological sub areas.
