Kev tsim kho thiab kev siv ntawm Crossed Multi-Arch Tsev cog khoom hauv Tropical Tuam Tshoj
Evolution ntawm Round Arc Tsev cog khoom Structure
Lub arch bar ntawm pem teb hom round-arch tsev cog khoom qauv (Daim duab 1a) muaj qhov ua tau zoo ntawm cov tshuab ua haujlwm zoo thiab cov qauv yooj yim rau nruab [11].Txawm li cas los xij, tseem muaj teeb meem xws li cov teeb meem hauv kev siv thiab kev khiav hauj lwm hauv cheeb tsam hauv qab lub xub pwg siab hauv tsev cog khoom lossis nruab nrab ntawm tsev cog khoom.Yog li ntawd, ib tug upright sab phab ntsa hom ib tug arch tsev cog khoom qauv (Daim duab 1b) tau tsim thaum lub sijhawm tsim khoom tiag.Cov qauv no daws qhov teeb meem ntawm kev siv lub xub pwg nyom.Txhawm rau txhawm rau txhim kho kev siv av thiab siv tag nrho cov khoom siv hauv tsev, ntau qhov kev sib tw puag ncig-arch tsev cog khoom (Daim duab 1c) tau tsim [12,13,14,15].Cov qauv no yog qhov dav thiab muaj kev siv av siab, uas tau maj mam tsim los rau hauv cov qauv tseem ceeb ntawm lub tsev cog khoom yas multi-span tam sim no [16].

Kev tsim kho thiab kev siv ntawm Crossed Multi-Arch Tsev cog khoom hauv Tropical Tuam Tshoj
Thaum siv ntau lub voj voog puag ncig arch yas tsev cog khoom siv rau hauv thaj chaw sov xws li Hainan, nws muaj qhov cua thiab tiv thaiv los nag.Piv txwv li, thaum muaj cua daj cua dub tshwm sim rau lub caij ntuj sov thiab lub caij nplooj zeeg, lub yob zaj duab xis qhov cua tshuab nyob rau sab saum toj ntawm lub tsev cog khoom tsis tuaj yeem kaw sai sai, thiab cov qoob loo hauv tsev cog khoom tuaj yeem raug puas los ntawm cua daj cua dub.Ntau tus neeg siv tau tso tseg tsis siv cov yob zaj duab xis qhov cua tshuab thiab npog lub ru tsev nrog yob zaj duab xis los xyuas kom meej qhov kev ua haujlwm tsis zoo ntawm lub tsev cog khoom, qhov cua hloov pauv tau daws los ntawm kev teeb tsa qhov cua ntawm cov arches;Yog li ntawd, ib tug multi-arch split qauv qauv tau tsim [17].Cov qauv no yog thawj zaug siv nyob rau hauv Sanya, Dongfang, Ledong, thiab lwm qhov chaw hauv Hainan rau cantaloupe tsev cog khoom, thiab nws sai sai tau los ua lub mainstream cantaloupe tsev cog khoom hom (Daim duab 2a) vim nws cov qauv yooj yim (tsis tas yuav xav txog kev thauj khoom typhoon; cov kem tuaj yeem tso ncaj qha rau hauv av yam tsis tau teeb tsa lub hauv paus) thiab tus nqi qis vim tias nws tsuas yog siv rau lub caij ntuj no thiab caij nplooj ntoos hlav (tsis muaj typhoon thiab nag los nag tsawg).Kev tshoov siab los ntawm qhov no, cov qauv tsim qauv tau ua qee qhov kev txhim kho (Daim duab 2b) mus rau ntau qhov sib cais qauv thiab siv rau lub caij ntuj sov thiab caij nplooj zeeg cog zaub hauv Hainan.Tom qab xyoo ntawm kev xyaum, tus qauv tau ua tiav cov txiaj ntsig zoo.Raws li nws yog tsuas yog siv rau off-season ntau lawm nyob rau hauv lub caij ntuj sov thiab lub caij nplooj zeeg, nws yog tsim nyog los xav txog cov kev tiv thaiv tiv thaiv typhoons.Ib lub hauv paus ywj pheej yuav tsum tau teeb tsa ntawm kem, cov ntaub ntawv loj thiab muaj zog yuav tsum tau siv, thiab tus nqi yuav tsum yog tsawg kawg ob zaug ntawm cantaloupe tsev cog khoom.
