临沂市城市地下空间资源地质调查评价研究

Geological Survey Evaluation and Study on Underground Space Resource in Linyi City

摘要:

临沂市城市建设发展迅速，城市面貌日新月异，但高楼密集、交通拥挤等问题也逐渐显现出来，城市建设需要更多的空间，开发利用城市地下空间已是首要解决的问题。临沂市位于沂沭断裂带与临沂单斜、平邑方城盆地多个地质单元的交会处，断裂构造发育，地震活动强烈，地质条件复杂，城市地下空间开发的影响因素众多，该文从水文及水文地质条件、工程地质条件、环境地质条件、人类工程活动等方面对临沂城市地下空间资源地质环境适宜性进行了分析研究，提出了其主要制约因素为极其发育的活动性断裂的看法，凡是活动性断裂对地下空间开发有影响的区域，均为地下空间资源开发制约区。评价结论对于提高城市发展格局、提高城市空间利用率、指导城市空间开发利用规划具有一定的参考意义。

Abstract:

Accompanying with rapid development of city construction, Linyi city has changed rapidly. But the problems about the dense buildings and traffic congestion have gradually emerged, city construction needs more space, development and utilization of city underground space is the primary problem to solve. Linyi city is located in the intersection of multiple geological unit, among the Yishu fault zone, Linyi monoclinic and Pingyi-Fangcheng basin, with developed faulted structures, strong seismic activities and complex geological conditions. Many factors influence the development of underground space. In this paper, from the aspects of hydrological and hydrogeological condition, engineering geological conditions, geological conditions, human engineering activities, geological environment of underground space resource in Linyi city has been anlyzed and studied. It is regarded that main restriction factor is the extremely developed active faults. All active faults which influenced the development of underground space in the area are the restricted areas to develop the underground space resource. The conclusion has certain reference significance to improve the development pattern, increase the space utilization ratio, guide the development and utilization of the city space.
