In this part , it is also found that the equivalent prismatic column , which is obtained based on the equal elastic critical load as the non - prismatic member , is not actually equivalent to the tapered column in inelastic stability , and the latter has higher load carrying capacity . finally , the behavior of tapered beam - column acted by combined axial load and transverse load has been investigated . a bending - thrust interaction curve is established which is similar to the ones for the design of prismatic members 三是研究了楔形變截面懸臂構(gòu)件在大端固定,小端同時承受橫向及軸向荷載共同作用下的強度和彎矩平面內(nèi)的穩(wěn)定,同時參考等截面構(gòu)件的設(shè)計公式,得到了用大端截面來表示的軸力p與彎矩m的之間的相關(guān)關(guān)系。
In this paper , we study the most serious damming section of the east - one main canal , which is from the entrance of the hao wan flume ( chainage12 + 123 . 6 ) to the exit of shang tian yuan tunnel ( chainage24 + 091 . 1 ) . the main content is analyzing the flow characteristic of the canal , setting up mathematical model of the discharge condition of the east - one main canal , according to the survey section and actual roughness factors , building , bend and so on , we divided the canal into more than loocaculation segments . each segment is calculated by microsoft excel electrical table through computer as permanent transition flow of non - prismatic channel 本論文研究的渠段為陸渾灌區(qū)東一干渠壅水最為嚴重的渠段,從郝灣渡槽進口(樁號12 + 123 . 6 )至上天院隧洞出口(樁號24 + 091 . 1 ) ,其主要內(nèi)容是,分析渠道水流特征,建立東一干渠輸水狀況的數(shù)學(xué)模型,根據(jù)測量斷面及實際糙率、建筑物、彎道等因素的不同,將渠道劃分成120多個計算段,每段按非棱柱體恒定漸變流,運用microsoftexcel電子表格進行編程計算。
