Assessment of regional crustal stability in Shenfu New Area of Liaoning Province, China
-
摘要: 在广泛收集资料和野外调查工作的基础上，经综合分析控制和影响区域地壳稳定性的主要因素和内外动力地质的耦合作用，基于ArcGIS平台采用多因素加权叠加分析方法开展了沈抚新区区域地壳稳定性评价研究。评价因素主要选取活动断裂、地震活动性和深部地球物理以及工程岩组、地形地貌与地表地质灾害等共12个影响因子，并依据评价因素的关联性和重要性进行分类赋值，进而建立了区域地壳稳定性评价模型。对沈抚新区的区域地壳稳定性进行了定量化评价。结果表明，沈抚新区以稳定区和次稳定区为主，面积为728.9 km2，占总面积的81.07%，有利于规划和建设。建议在地下工程穿越不稳定区和次不稳定区时，要采取必要的工程措施，确保基础和边坡的稳定性。规划的地铁9号线主要穿越次不稳定区和次稳定区。施工带在埋深15~25 m之间，该段地层主要为卵砾石堆积层、泥包砾堆积层与变质片麻岩强风化带及其交接部位，施工带处于地下水浸没带或变动带，其支护比较困难，建议尽早确定合理的施工方案，保障施工顺利和安全，此外还需要采取一定降水防腐措施。

Abstract: In this paper, the main factors controlling and influencing regional crustal stability as well as the coupling action of internal and external dynamic geology in Shenfu New Area were analyzed, using both previous findings and field survey results. Based on the GIS platform, the regional crustal stability assessment was carried out through the multi-factor weighted superposition analysis method. Twelve influencing factors were selected, including fault activity, seismicity, deep geophysical status, engineering rock group, topography and surface geological hazards. The regional crustal stability assessment model was established in terms of relevance and importance of the influencing factors, through which to quantitatively assess the regional crustal stability of Shenfu New Area. And the results show that Shenfu New Area is dominated by the stable and sub-stable areas covering 728.9 km2, accounting for 81.07% of the total area, which is conducive to the planning and construction in this area. Necessary engineering measures are recommended to ensure the stability of foundation and slope when underground engineering, such as the construction of the planned Metro Line 9 at a depth of 15~25 meters, passes through the unstable and sub-unstable areas. The strata in the construction section of Metro Line 9 are generally weathering zones and junction areas of oval-gravel accumulation, mud-clastic accumulation and metamorphic gneiss, situated in groundwater immersed zones or changing zones, which is hard to be provided with protection and support. It is suggested that reasonable construction scheme should be determined as soon as possible to ensure a smooth and safe construction, and precipitation and anticorrosion measures are needed. -
