发布时间：2018-10-10 07:34
【摘要】：宝坻区位于京津唐的中心地带，在经济发展中具有重要作用。以往本区的大部分工作都在上世纪90年代以前，水文地质方面的研究都偏重于某一特定区域，尤其是对于地下水资源的计算，因而需要采取更加科学合理的方法进行水资源评价。本文以天津市宝坻区综合地质调查项目为依托，着重对工作区域的水文地质工作进行重点讨论、研究，在前人工作基础上进行归纳整理开展水文地质调查。 本次工作收集到各类资料100多份，其中综合地质调查报告46份、岩土工程勘察报告114份、地下水动态观测年鉴10份、钻孔678个。资料内容涵盖基础地质、水文地质、工程地质、环境地质、地球化学、地球物理及遥感地质等多方面，涉及到的部门包括地矿、地震、水利、规划、环保、建筑、冶金、油田等多家单位。在大量收集资料的基础上，有针对性的进行了野外施工和室内实验，其中水工环地质灾害测量1510km2、地质遥感解译3159km2、工程地质钻探1335m、EH4电磁探深203点、标准贯入试验230次、土工试验705件、颗粒分析103件、水质简分析40件、水质全分析68件、工程点测量40点，，为更加科学合理科学的评价宝坻区的水资源情况提供真实的数据基础。 通过此次项目，了解了本区明水资源的分布情况主要受地质构造和古水系的控制，本区咸淡水界分布与宝坻断裂走向大体吻合，地下水的赋存条件、补径排特征，本区的为有开发潜力区，地下水质量不乐观，水质较差，由于不合理开采地下水使得本区存在地面沉降和地裂缝等地质灾害。
[Abstract]:Baodi District, located in the heart of Beijing, Tianjin and Tang, plays an important role in economic development. In the past, most of the work in this area was before the 1990s, and hydrogeological studies focused on a particular area, especially for the calculation of groundwater resources. Therefore, it is necessary to adopt more scientific and reasonable methods to evaluate water resources. Based on the comprehensive geological survey project in Baodi District of Tianjin, this paper focuses on the discussion of hydrogeology work in the working area, studies it and carries out hydrogeological survey on the basis of previous work. More than 100 kinds of data were collected in this work, including 46 comprehensive geological survey reports, 114 geotechnical engineering survey reports, 10 groundwater dynamic observation yearbooks, and 678 boreholes. The data cover basic geology, hydrogeology, engineering geology, environmental geology, geochemistry, geophysics and remote sensing geology. The departments involved include geology, earthquake, water conservancy, planning, environmental protection, construction, metallurgy, etc. Many units such as oil fields. On the basis of a large amount of data collected, field construction and indoor experiments were carried out, including 1510km2 of hydro-environmental geological hazard survey, 3159km2 interpretation of geological remote sensing, 203 points of electromagnetic exploration depth of 1335mEH4 in engineering geological drilling, 230 standard penetration tests. 705 geotechnical tests, 103 particle analysis, 40 water quality analysis, 68 total water quality analysis and 40 site measurements provide a real data basis for more scientific and scientific evaluation of water resources in Baodi district. Through this project, it is understood that the distribution of water resources in this area is mainly controlled by geological structure and paleo-water system, the distribution of salt and light water boundary in this area is roughly consistent with Baodi fault strike, the occurrence conditions of groundwater, the characteristics of recharge and drainage, The groundwater quality is not optimistic and the water quality is poor. Because of unreasonable exploitation of groundwater, there are geological disasters such as ground subsidence and ground fissures in this area.
