Cov nplai ntawm yas multi-span tsev xog paj Zuag qhia tag nrho ntev ntawm lub tsev cog khoom yas multi-span feem ntau yog 40-60 meters, thiab qhov ntev tshaj yog tsis ntau tshaj 100 meters, uas yog ntev dhau lawm thiab tsis yooj yim los tswj. Lub tsev yog 10-20 meters dav, thiab lub tank tsis zoo cua. Nyob rau hauv cov ntaub ntawv ntawm tib cheeb tsam thiab lwm yam kev mob, qhov loj dua qhov ntev ntawm lub tsev cog khoom yas multi-span, qhov hnyav dua ko taw ntawm lub koov load, thiab cov txheeb ze txo cov cua tsis kam. Nyob rau tib lub sijhawm, nws tseem nyuaj rau lub tsev los hla dhau cuaj lub tsev. Cov zaj duab xis tsis yooj yim rau zawm, thiab nws yooj yim los tsim kua muag yog tias nws vibrates nquag. Piv txwv li, qhov me me ntawm qhov ntev ntawm lub tsev, qhov denser lub arches thiab lub zog cua tiv thaiv. Qhov piv ntawm qhov ntev mus rau qhov dav ntawm cov yas multi-span tsev cog khoom. Piv txwv li, qhov ntev ntawm lub canopy yog 100 meters, qhov dav ntawm lub tsev yog 10 meters, thiab qhov ratio ntawm dav mus rau ntev yog 10/l00=0.1. Lwm qhov piv txwv yog tias qhov ntev ntawm lub tsev yog 50 meters, thiab qhov dav ntawm lub tsev yog 20 meters. Tag nrho qhov piv yog 20/50=0.4. Qhov ntau dua qhov sib piv, qhov ntau dua qhov cua lub zog gravitational (los yog rub lub zog), yog li nyob rau hauv tib yam kev mob, qhov sib piv me me, lub zog cua tsis kam. Nyob rau tib lub sijhawm, lub tsev cog khoom nrog qhov ntev ntawm 100 meters thiab qhov dav ntawm 10 meters muaj ib puag ncig ntawm 220 meters; lub tsev xog paj nrog qhov ntev ntawm 50 meters thiab dav ntawm 20 meters muaj ib ncig ntawm 140 meters. Ob qhov chaw sib npaug, thiab qhov sib txawv ntawm thaj tsam yog li 0.6 npaug. Yog hais tias cov npoo yog faus rau hauv av, qhov qub yuav raug muab faus ntau dua nruj, thiab cov cua tiv thaiv yuav zoo dua. Thaum txiav txim siab qhov ntev thiab qhov dav ntawm lub flail, pab pawg yuav tsum tau tsim raws li qhov tshwj xeeb hauv zos. Qhov siab ntawm yas multi-span tsev xog paj: rau ib lub tsev cog khoom ib zaug, qhov siab yam tsawg kawg nkaus yog 1.8-2.4 meters, qhov nruab nrab sab qhov siab yog 1.6-2.0 meters , thiab sab qhov siab yog 1.3-1.5 meters. Qhov siab dua lub tsev xog paj, qhov cua nrawm dua thiab siab dua nws yuav tiv taus. Yog li ntawd, qhov siab ntawm lub tsev cog khoom yas multi-span yog tsim los ua kom tau raws li cov kev xav tau ntawm kev loj hlob ntawm cov zaub thiab ua kom yooj yim rau kev khiav lag luam thiab kev tswj hwm, thiab nws yuav tsum luv luv li sai tau los txo cov cua puas.
