温州市区域地壳稳定性评价
|
摘要
论文以温州市全地区为研究区域,通过以构造稳定性为主,配合介质(岩土体)稳定性和地面稳定性的研究,探讨温州市区域地壳稳定性情况。
在收集了前人地质资料的基础上,结合大量的野外地质调查,对温州地区主要断裂的分布情况、活动性做了系统地研究,认为影响温州地区稳定性的主要活动断裂有4条,同时,也对温州地区的新构造运动及构造应力场、岩土体力学性质、地震活动及其危险性、地面沉降和地热异常等6项主要影响因子做了初步的探讨分析。
在确定了影响区域地壳稳定性的主要因素后,通过模糊数学的方法分析以上6个影响因子,将各因素指标化,确定各个指标隶属于稳定级别的隶属函数,运用模糊数学中的模糊综合评判法对温州地区区域地壳稳定性进行模糊综合评判,进而对本区域进行了初步分区和定量化评价。在稳定性分析、模糊评判的基础上,最终判定研究区可圈定为三个稳定性级别:相对稳定区、相对较稳定区和相对不稳定区。其中相对稳定区所占面积约为整个研究区的一半;相对不稳定区面积较小,造成相对较不稳定的关键性因素是地震、活动断裂和外动力作用。
结论认为:温州地区断裂活动性不是特别强,地震震级不是很高,烈度也不是很高,因此整体稳定性较好。但外围地震带对本区东部有一定影响,区内北东向与北西向断裂带的交汇部位今后发震的可能性也较大,在今后城市建设规划和重大工程选址中应予充分考虑。
Taking Wenzhou city as research area, the regional crustal stability in Wenzhou city is discussed in this paper, based on the studies of the tectonic stability, the stability of rock, soil medium and surface stability.
Through collecting many datas, the main faults of the Wenzhou researched and explored systemically, and initially defines that there are 4 main activitily faults to influence stability of Wenzhou. Based on this, the paper also researches systemically about Cenozoic and recent techonic activity, the crustal surface structure and rock-soil mechanical property, seismic activity and risk, surface sedimentation and terrestrial heat abnormity.
After confirmed the main factors in influencing the regional crustal stability,there are 6 main genes in this paper applying to the fuzzy mathematics comprehensive assessment method. Then the factors of dominating regional crustal stability are transformed into numerical values, and the subjective function of numerical value of every factor is established. Finally by using comprehensive fuzzy mathematics method, crustal stability evaluate of Wenzhou city is accomplished.Based on stable analysis and fuzzy comprehensive evaluation, the stable grade of each subzone of Wenzhou city is determined.Based the stability analyses and fuzzy mathematics' method, this research area to be possible finally to plot out three stable rank: the relative stability region, compared the stability region and the relative not stability region relatively, the relative stability region of area is about half of the whole Wenzhou city, the relative not stability region of area is smaller, and the main factors working on the relative not stability region are earthquake, activitily faults and effect out side of driver.
Conclusion:the activity of faults in Wenzhou region is not stronger, and the earthquake level and intensity is not higher. So the whole crustal stability is better. But earthquake belt peripherally have effect in east region to a certainty, and the some region where northeast faults and northwest faults are join arose earthquake more impossibly. So in city building and selecting important project site in future we shall take into account those.
