【正文】 rosperously developed in China. According to the practical situation of one freeway construction project, a new resolution is proposed by this paper, based on some accidents statistical data. Further more, qualitative and quantitative assessment is carried out from seven aspects, viz. general layout, construction site, roadbed, tunnel, fie in tunnel, bridge and road system. The real case introduced by this paper, can be the reference to some similar projects, and it must be significant to the improvement of safety level in later freeway construction.Keyword:freeway, construction project, safety preassessment。關(guān)鍵詞:高速公路、建設(shè)工程、安全預(yù)評(píng)價(jià);Study and Application on Safety Preassessment of Freeway Construction ProjectMa Haitao1, Yang Runlin2, Ren Zhigang1, Zhang Zhizeng3( Academy of Safety amp。高速公路建設(shè)工程安全預(yù)評(píng)價(jià)研究作者:日期:高速公路建設(shè)工程安全預(yù)評(píng)價(jià)研究及工程應(yīng)用馬海濤1 楊潤(rùn)林2 任智剛1 張志增3(1.中國(guó)安全生產(chǎn)科學(xué)研究院 2.北京科技大學(xué) 3.清華大學(xué))摘 要:本文針對(duì)我國(guó)如火如荼的高速公路建設(shè)工程中日益突顯的安全問(wèn)題,在事故統(tǒng)計(jì)分析的基礎(chǔ)上,結(jié)合某山區(qū)高速公路建設(shè)工程的實(shí)際情況,提出了高速公路工程安全評(píng)價(jià)工作的新思路。針對(duì)公路工程的特點(diǎn),分別從總體方案、施工現(xiàn)場(chǎng)、路基工程、隧道工程、隧道火災(zāi)、橋梁工程、公路系統(tǒng)等7個(gè)方面的定性、定量評(píng)價(jià)進(jìn)行分析,可以作為今后高速公路安全評(píng)價(jià)項(xiàng)目的參考案例,對(duì)促進(jìn)高速公路建設(shè)工程安全水平的提升有積極的影響意義。 Technology, of Science
