【摘要】：隨著經(jīng)濟(jì)的高速發(fā)展,我國(guó)水電行業(yè)得到了大力的開(kāi)發(fā),在開(kāi)發(fā)的同時(shí)安全事故頻發(fā),造成了巨大的財(cái)產(chǎn)損失與人員傷亡。由于水電工程施工復(fù)雜,涉及面廣,不安全因素較多,容易導(dǎo)致事故發(fā)生。因此為了使得水電工程施工安全進(jìn)行,做好施工安全隱患評(píng)價(jià)是一種有效的辦法。企業(yè)通過(guò)安全評(píng)價(jià)可以合理分析出施工過(guò)程中的隱患現(xiàn)狀,進(jìn)而做好相應(yīng)隱患的排查與整改,保證了施工安全進(jìn)行。本文通過(guò)研究國(guó)內(nèi)外安全評(píng)價(jià)方法的現(xiàn)狀,根據(jù)我國(guó)相關(guān)法律法規(guī)以及水電工程施工的特點(diǎn),再結(jié)合專家意見(jiàn),構(gòu)建了一套水電工程施工安全隱患評(píng)價(jià)指標(biāo)體系。而目前,采用模糊綜合評(píng)價(jià)和人工神經(jīng)網(wǎng)絡(luò)對(duì)工程安全隱患問(wèn)題的研究也逐漸增多。人工神經(jīng)網(wǎng)絡(luò)具有很強(qiáng)的容錯(cuò)性以及聯(lián)想能力,能夠很好地反映出外界輸入信息的本質(zhì)特征,但是它不具有處理模糊信息的能力,不能有效的利用專家經(jīng)驗(yàn)知識(shí)。水電工程施工的安全因素有許多的不確定性,具有很強(qiáng)的模糊性,這就導(dǎo)致了人工神經(jīng)網(wǎng)絡(luò)運(yùn)用的局限。模糊綜合評(píng)價(jià)法能很好地處理模糊信息并利用專家知識(shí)經(jīng)驗(yàn),但是其運(yùn)算速度慢、精度低,因此結(jié)合兩種評(píng)價(jià)方法能充分發(fā)揮兩者的優(yōu)勢(shì)。本文以水電工程施工安全隱患為研究對(duì)象,采用模糊綜合評(píng)價(jià)與BP神經(jīng)網(wǎng)絡(luò)相結(jié)合的方法,基于MATLAB神經(jīng)網(wǎng)絡(luò)工具箱建立了基于模糊綜合評(píng)價(jià)和BP神經(jīng)網(wǎng)絡(luò)的模糊神經(jīng)網(wǎng)絡(luò)評(píng)價(jià)模型。利用建立好的模糊神經(jīng)網(wǎng)絡(luò)模型對(duì)實(shí)際工程進(jìn)行安全隱患評(píng)價(jià),運(yùn)用模糊綜合評(píng)價(jià)法對(duì)其結(jié)果進(jìn)行驗(yàn)證,并將得到的評(píng)價(jià)結(jié)果與實(shí)際隱患排查情況對(duì)比分析,證實(shí)了方法的實(shí)際意義。本文提出的模糊神經(jīng)網(wǎng)絡(luò)模型是對(duì)水電工程施工安全隱患進(jìn)行評(píng)價(jià)的一種新方法,對(duì)于水電工程施工過(guò)程的安全隱患排查具有一定的參考意義。
[Abstract]:With the rapid development of economy, the hydropower industry in our country has been vigorously developed, and the frequent safety accidents have caused huge property losses and casualties. Due to the complex construction of hydropower projects, involving a wide range of unsafe factors, easily lead to accidents. Therefore, in order to make the construction safety of hydropower project, it is an effective method to evaluate the hidden dangers of construction safety. The present situation of hidden dangers in construction process can be reasonably analyzed through safety evaluation, and the corresponding hidden dangers can be checked and rectified to ensure the safety of construction. By studying the present situation of safety evaluation methods at home and abroad, according to the relevant laws and regulations of our country and the characteristics of hydropower project construction, and combining with expert opinion, this paper constructs a set of evaluation index system of safety hidden danger in hydropower project construction. At present, fuzzy comprehensive evaluation and artificial neural network are used to study the hidden dangers of engineering safety. Artificial neural network has strong fault tolerance and association ability, which can well reflect the essential characteristics of external input information, but it does not have the ability to deal with fuzzy information, and can not effectively use expert experience knowledge. There are many uncertainties and strong fuzziness in the construction of hydropower engineering, which leads to the limitation of artificial neural network. Fuzzy comprehensive evaluation method can deal with fuzzy information well and make use of expert knowledge experience, but its operation speed is slow and its precision is low. Therefore, the two evaluation methods can give full play to their advantages. This paper takes the hidden trouble of hydropower construction as the research object, and adopts the method of combining fuzzy comprehensive evaluation with BP neural network. A fuzzy neural network evaluation model based on fuzzy comprehensive evaluation and BP neural network is established based on MATLAB neural network toolbox. The fuzzy neural network model is used to evaluate the hidden dangers of practical projects, the fuzzy comprehensive evaluation method is used to verify the results, and the results are compared with the actual hidden dangers. The practical significance of the method is proved. The fuzzy neural network model proposed in this paper is a new method to evaluate the hidden dangers of construction of hydropower projects, which has a certain reference significance for the investigation of hidden dangers in the construction process of hydropower projects.
