【摘要】 哈尔滨市目前的城市发展逐步向城区周边伸展，很大程度加大了城区的建设面积和发展速度，因此，需要一个更为全面立体的工程地质条件研究，同时，经济的高速发展，交通拥挤、空间缺乏、空气污染等矛盾在哈尔滨市也日益严峻，严重制约着城市发展和环境质量的提高，查明我市地下空间浅部（0-10m）、较浅部(10-30m)处工程开发适宜性，对我市合理、有序、可持续地开发地下空间资源有着重要意义，而充分利用可开发地下空间资源又是适应城市高速、稳定的发展的有利条件。本文在充分了解哈尔滨市核心城区的自然地理、经济状况以及区域地质背景的基础上，通过哈尔滨城市地质调查岩土体三维工程地质结构与地下空间资源调查专题的野外钻孔和室内岩土试验等数据处理资料，开展本区工程地质三维结构研究；并在此基础上，结合本区存在的不良地质体和地下水分布特征，对本区进行工程地质分区划分；在充分掌握全区工程地质三维结构和地质分区基础上，基于层次分析法的多因素权重指标函数法，建立地下空间工程难度评估模型，并利用这一模型，对哈尔滨（四环以内）地下空间适宜性进行等级划分。通过对区内钻孔的地层和物理性质指标分析，将工作区4.5-108.1m深度的第四系工程地质层，划分为12主层，46个亚层和7个次亚层。并依据岩土体地层时代、岩性和成因，查明本区工程地质三维结构类型分为单层结构、双层结构和多层结构三大类，其中单层结构具体可细分为单一粘性土与单一非粘性土两种类型，双层结构可细分为上部厚层粘性土，下部非粘土、上部中厚层粘性土，下部非粘土与上部薄层粘性土，下部非粘土三种类型，多层结构细分为上部厚层粘性土的多层结构、上部中厚层粘性土的多层结构与上部为非粘性土的多层结构三种类型。根据哈尔滨城市工程地质条件特征，工程地质分区采用三级划分，按地貌成因类型及成因形态进行一级划分，确定工作地质区；然后按地貌单元与区域地壳稳定性进行二级划分，确定工程地质亚区；最后根据场地工程地质条件划分为五个段。即好段、较好段、中等、较差段、差段，最终将工作区划分为3个工程地质区、10个工程地质亚区、19个工程地质段。对四环内地下空间适宜性进行分区,结果表明区内浅层地下空间适宜性可分为适宜区、较适宜区、中等适宜区；次浅层地下空间适宜性分为较适宜区、中等适宜区、适宜性差区及不适宜区。为哈尔滨市经济建设、市政规划以及资源的合理利用提供了重要的地学依据。更多还原

【Abstract】 At current，the trend of urban development is stretching around outside urban whichgradually increase the construction space of the urban area and the speed of thedevelopment,therefore,there is a need on research of more comprehensivethree-dimensional engineering geological conditions. At the same time, the contradictionamong the high speed development of economy, traffic congestion, lack of space, airpollution in Harbin become increasingly serious， seriously restricting the urbandevelopment and the improvement of environmental quality，finding out the engineeringdevelopment suitability in shallow underground space from0to10m and from10to30mis significant for the reasonable, orderly and sustainable development of the undergroundspace resource in Harbin，and making full use of underground space resource is thefavorable condition of the city high speed and stable development.Based on the full understanding of natural geography, economic status and regionalgeological background in key region of Harbin, and using the material of field drilling andindoor geotechnical test data processing from the geotechnical body three-dimensionalengineering geological structure and the underground space resource investigation whichis one project of the urban geological survey, to carry out the engineering geologythree-dimensional structure research, And on this basis, combining with the existence ofbad geological body and underground water distribution characteristics, to carry out thezoning of engineering geology, on finding out the engineering geology three-dimensionalstructure and geological zoning basis, to make up the establishment of underground spaceproject difficulty evaluation model that based on analytic hierarchy process (ahp) ofmultiple factors weight index function method, and using this model to find out theunderground space Suitability evaluation within the fourth ring region in Harbin. Based on analysis of drilling formation and physical properties index, the Quaternarystrata that stretch from4.5to108.1m in thickness in Harbin’s key region is divided intotwelve main layers, forty-six sub layers and seven secondary sub layers. combined withthe stratigraphic age, lithology and causes of formation of rock mass and soil, the paperfind out the engineering geology three-dimensional structure types which are divided intothree categories which are single layer structure, double layer structure and multilayerstructure. The single structure can be divided into single cohesive soil and single inviscidsoil. The double layer structure can be divided into three types which are thick layer ofcohesive soil in the upper layer and inviscid soil in the lower layer, medium thick cohesivesoil in the upper layer and inviscid soil in the lower layer, and the thin layer viscous soil inthe upper layer and inviscid soil in the lower layer. And the multilayer structure can bedivided into three types which are multilayer structure distributing thick cohesive soillayer, medium thickness cohesive soil layer and inviscid soil layer in the upper.According to the engineering geology conditions of Harbin, engineering geologicalzone divided in three levels. Based on landform genetic types and causes for the first leveldivision, determined the engineering geology area; Then according to the geomorphic unitand regional crustal stability for the second level division, determined the engineeringgeology sub-area; According to the site engineering geological condition divided the areainto five section. That is excellent section, good section, medium, poor section, poorersection, eventually work region can be divided into three engineering geology area,10engineering geology sub-region,19engineering geological section.Results of suitability zoning of underground space within the fourth ring region inHarbin show that Shallow underground space can be divided into the suitable division,better suitable, medium suitable area, and the deeper Shallow underground space can bedivided into the better suitable area, medium suitable area, poor suitable area, unsuitablearea. The data provides an important geological basis for economic construction,municipal planning and the resources reasonable use of Harbin.更多还原
