【摘要】：自2000年以來,我軍工程部隊越來越多的承擔(dān)了國家重大基礎(chǔ)建設(shè)任務(wù),山體開挖施工也是其中一類,隨著參與山體開挖施工的部隊數(shù)量不斷增加、作業(yè)難度和任務(wù)的緊迫性提升,施工過程中滑坡事故發(fā)生的頻率越來越高,即損失國防軍事力量,也會延誤的是國防軍事戰(zhàn)略部署,對國防事業(yè)是極大的威脅。為了加強工程部隊的安全管理水平,提高對滑坡事故的預(yù)防控制能力,本文系統(tǒng)梳理了國內(nèi)外滑坡事故的自然成因與人為成因的基礎(chǔ)上,結(jié)合我軍工程部隊存在的問題,展開針對部隊施工中滑坡事故的風(fēng)險評估與策略研究。利用系統(tǒng)科學(xué)的理論與方法,首先將部隊工程部隊山體施工工程視為系統(tǒng),依據(jù)系統(tǒng)的要素、過程等維度劃分,構(gòu)建了工程的系統(tǒng)結(jié)構(gòu),并據(jù)此進行工程中滑坡事故的風(fēng)險因素辨識與分析,共包含籌備與施工兩大時間階段中的人、機、管、環(huán)四類因素。在施工中滑坡事故的風(fēng)險評價方法與策略研究中,利用SMARTER原則,并結(jié)合符號化編碼的方法,構(gòu)建了滑坡事故的全過程全要素的風(fēng)險評價指標(biāo)體系,通過問卷調(diào)查的方法確定了指標(biāo)的優(yōu)選與權(quán)重的確定�；率鹿实姆旨墧�(shù)學(xué)模型共包含兩類,一類是各階段滑坡事故的綜合風(fēng)險指數(shù);另一類是各階段滑坡事故的要素風(fēng)險指數(shù),這樣設(shè)定的目的是為了后續(xù)的預(yù)控策略體系建立提供對應(yīng)的分級依據(jù)。預(yù)控策略體系由兩個步驟組成,首先由階段的綜合風(fēng)險指數(shù)等級確定總體策略,然后由階段內(nèi)各要素的風(fēng)險指數(shù)等級確定針對要素的具體控制措施。最后,通過對我軍某工程部隊的一項山體施工工程進行實證研究,對兩個階段各自的綜合風(fēng)險與總體策略、要素風(fēng)險與具體措施進行了評價與分析,為工程部隊施工提供了方法支持,并證明該方法可對部隊各項山體施工的滑坡事故綜合風(fēng)險進行計算和評價,同時提供較為完善的策略依據(jù)。
[Abstract]:Since 2000, the engineering units of our army have assumed more and more important national basic construction tasks, and mountain excavation construction is also one of them. With the increasing number of troops involved in mountain excavation construction, The difficulty of the operation and the urgency of the task are increased, and the frequency of landslide accidents in the construction process is increasing. That is to say, the loss of national defense and military strength will also delay the deployment of the national defense military strategy. In order to strengthen the safety management level of engineering troops and improve the ability to prevent and control landslide accidents, this paper systematically combs the natural and man-made causes of landslide accidents at home and abroad. Combined with the problems existing in our army's engineering units, the risk assessment and strategy study of landslide accidents in army construction are carried out. By using the theory and method of system science, the mountain construction engineering of army engineering units is first regarded as a system. The system structure of the project is constructed according to the dimensionality of system elements and process, and the risk factors of landslide accident in engineering are identified and analyzed accordingly. The system consists of human, machine and management in the two stages of preparation and construction. In the study of risk assessment method and strategy of landslide accident in construction, the risk evaluation index system of the whole process of landslide accident is constructed by using SMARTER principle and symbolic coding method. The optimal selection of indicators and the determination of weights are determined by the method of questionnaire survey. There are two types of mathematical models for landslide accidents, one is the comprehensive risk index of landslide accidents in each stage, and the other is the comprehensive risk index of landslide accidents in different stages. The other is the factor risk index of landslide accident in each stage, so the purpose of setting up is to provide the corresponding grading basis for the subsequent establishment of the pre-control strategy system. The pre-control strategy system consists of two steps. First, the overall strategy is determined by the comprehensive risk index grade of the stage, and then the specific control measures for the elements are determined by the risk index grade of each element in the stage. Based on an empirical study of a mountain construction project in a certain engineering unit of our army, the comprehensive risk and overall strategy, factor risk and concrete measures of the two stages are evaluated and analyzed, which provides method support for the construction of the engineering unit. It is proved that this method can be used to calculate and evaluate the comprehensive risk of landslide accidents during the construction of various mountain bodies in the army, and to provide a more perfect strategic basis at the same time.
