Extended Abstract

typhoon affected the number of bridge site area ratio of t he total area in the north of bridgesite to reach 84.9% of Nantong, Changshu City, south of the bridge site area 87.7%. Seriouslyaffect the ap pearance of the bridge district board level 8 ty phoon gusts above average 0.78.The impact of typhoon winds, gale winds occurred mainly in the southeast and the north sidedirection, while the s outhwest wind appears less likely. Seriously affect the bridge site are afor more than eight h ours for the i mpact of ty phoon winds in s ummer and au tumn 6 to 10months, concentrated i n J uly-September, in the b ridge ar ea n orth of Nant ong, Ch angshu,respectively, south of the typhoon winds of the total 93.3%, 88.4%, Among them, most likelyin August, in the bridge north and south, respectively, 34.9%, 44.4%.(2) This article Sutong a case, the bridge district board 8 ty phoon winds of expectedloss index of 0.2821, the potential economic losses of 206.75 million yuan, accounting for theprovince typhoon expected loss index of 48%, which bridge site area along the coast o f thespecial geographical location and Nantong in Jiangsu Province, Changshu is the place acr ossthe province is closely related to a major hurricane.(3) by S u T ong B ridge di saster of ty phoon winds al so show t hat l arge-scaleconstruction p roject p lanning and future operations should p ay particular attention to thelanding h ere, cros sing the ty phoon disasters and ex ternal i nfluence airfl ow caused by thetyphoon wind weather, construction tower cranes, etc. facilities should avoid setting up in thewind direction to av oid the risk of disasters caused by typhoon winds. The study also fou ndthat, even if the t yphoon winds in J une and in October the chances appear s maller, but stillgreat harm. Therefore, the typhoon wind project area should be proactive disaster prevention,prevention, and should establish project areas for environmental monitoring weather warningsystem, to receive an d di stribute t imely ty phoon f orecasting an d warning, a nd acorresponding typhoon emergency response procedures.In general, the more developed areas of regional economic population density, industrialdensity, the higher the level of industrialization, in which case a small p robability of extremeweather di sasters are causin g h uge eco nomic los ses, th e p aper winds o f T yphoon Brid geDisaster preliminary risk a ssessment studies t o try simil ar proj ects ca n pro vide a r eferencemeteorological disaster assessment. It is noteworthy that the typhoon winds and torrential raindisaster incl udes t wo as pects of dis asters, this d isaster l oss estimates c onsider only thetyphoon winds, expected yield loss index and the calculation of the potential economic loss islimited, we will be strong winds and typhoons typhoons and storms in the risk assessment andrisk management typhoon further study.References[1] JIANG D L, YAN J Y.
