Study On The Gis-based Visualized Damage Evaluation System For Constructions In Subsidence Area

Over the past30years, rapid development of construction industry in our country,brings us a huge wealth. At the same time, it brings us all kinds of pressure, resourceconsumption is too fast, air quality drops down, all kinds of environmental pollutionoccure. In this case, the state began to vigorously promote circulation, green, andsustainable development model in all walks of life. Green mode of the constructionindustry is to change the traditional way of development which is high energyconsumption, high emission, low outputting and low efficiency, and take the developthe economic transformation and upgrade technology as aims. This paper mainlydiscusses the related contents of construction technology upgrade, clarify withtechnology as the main point, to realize the sustainable development of constructionindustry through technical upgrading.This article summarizes the related content about technology upgrading under thedevelopment of green construction from the perspective of basic theory. Firstly,itanalyzes the present stage green mode of the construction industry, Secondly, itsummarizes the current situation of the development of technology of constructionenterprises.The construction enterprises in construction enterprises is the final foothold of thispaper, through the construction enterprise technology summary and analysis of thestatus, this article put forward external and internal path measures of the technologyupgrade. In order to get complete judgment and analysis about the upgrade of thetechnology of the construction enterprise, this paper uses the combination ofqualitative and quantitative, theoretical study and practice of combining researchmethods, taking a mode of green construction enterprise development as thebackground, it extract the key factors which affect the construction enterprisetechnology upgrades. Then, it builds evaluation model of the construction enterprisetechnology upgrades degree under the green development mode, for getting betterunderstanding and analysis of the construction enterprise technology upgrades,providing service for the construction industry technology upgrades.In the end of the paper, it uses a field survey of the construction enterprise to verifythe applicability of the model, the results are in conformity with the actual circumstances of the enterprise, confirmed the model’s applicability. And by analyzing the results, weget the enterprise’s current development situation, and put forward some opinions fortechnology upgrades. But there are still some defects and the insufficiency in this article,also need to perfect further.
