【摘要】：為定量評(píng)估化工區(qū)域風(fēng)險(xiǎn),結(jié)合信息擴(kuò)散法和網(wǎng)格劃分技術(shù),利用MATLAB編寫個(gè)人風(fēng)險(xiǎn)計(jì)算程序�；谝酝愃剖鹿式y(tǒng)計(jì)數(shù)據(jù),通過(guò)信息擴(kuò)散法確定某化工區(qū)域火災(zāi)爆炸事故發(fā)生頻率,得到事故頻率與指標(biāo)論域之間的擬合函數(shù);利用網(wǎng)格劃分技術(shù)計(jì)算各重大危險(xiǎn)源發(fā)生火災(zāi)爆炸事故引起的個(gè)人風(fēng)險(xiǎn)網(wǎng)格疊加矩陣。結(jié)果表明:該化工區(qū)域內(nèi)個(gè)人風(fēng)險(xiǎn)最大值為2.57×10-3,事故疊加效應(yīng)造成個(gè)人風(fēng)險(xiǎn)最大值增加了1個(gè)數(shù)量級(jí);根據(jù)個(gè)人風(fēng)險(xiǎn)標(biāo)準(zhǔn),當(dāng)化工區(qū)域個(gè)人風(fēng)險(xiǎn)值大于1×10-3時(shí)為不可容許風(fēng)險(xiǎn)水平,必須采取有效措施。
[Abstract]:In order to quantitatively evaluate the regional risk of chemical industry, the personal risk calculation program is compiled by using MATLAB in combination with information diffusion method and grid division technology. Based on the statistical data of similar accidents in the past, the frequency of fire and explosion accidents in a chemical region is determined by the information diffusion method, and the fitting function between the accident frequency and the index field is obtained. The superposition matrix of personal risk grid caused by fire and explosion accident of every major hazard source is calculated by using grid partitioning technique. The results show that the maximum value of personal risk is 2.57 脳 10 ~ (-3) and the maximum value of personal risk is increased by one order of magnitude due to the superposition effect of accident, according to the personal risk standard, the individual risk level is not allowed when the personal risk value is greater than 1 脳 10 ~ (-3). Effective measures must be taken.
