第五章成橋檢算5.1檢算卡的填寫成橋檢算數(shù)據(jù)卡與估索卡既有聯(lián)系又有區(qū)別。檢算卡是在估索卡原有數(shù)據(jù)的基礎(chǔ)上增加了與所配預(yù)應(yīng)力筋及徐變等因素有關(guān)的控制信息。有以下五種荷載組合：第一種：汽車+二期恒載+第一組集中力+第一組強(qiáng)迫位移+第一組溫度力第二種：掛車+二期恒載第三種：汽車+二期恒載+第一組集中力+第二組強(qiáng)迫位移+第二組溫度力第四種：滿人+二期恒載+第一組集中力+第一組強(qiáng)迫位移+第一組溫度力第五種：掛車+二期恒載+第一組集中力+第一組強(qiáng)迫位移+第一組溫度力其數(shù)據(jù)卡的填寫與估索卡類似，具體填寫參見附錄。5.2溫度力和強(qiáng)迫位移對(duì)結(jié)構(gòu)內(nèi)力的影響溫度力對(duì)結(jié)構(gòu)內(nèi)力的影響1.溫度力的計(jì)算與其他物體一樣，熱脹冷縮也是橋梁結(jié)構(gòu)的固有屬性之一。橋梁是置于大氣的結(jié)構(gòu)。溫度毫不例外的對(duì)橋梁產(chǎn)生影響。溫度影響包括年溫差影響與局部溫度影響。年溫差影響指氣溫隨季節(jié)變化對(duì)結(jié)構(gòu)所起的作用，一般假定溫度沿結(jié)構(gòu)物截面高度方向均勻變化。對(duì)無(wú)水平約束的連續(xù)梁橋，年溫差只引起結(jié)構(gòu)的均勻收縮，而不產(chǎn)生溫度次應(yīng)力。局部溫差一般指日照溫差或混凝土水化熱影響。水化熱影響較為復(fù)雜，且在施工中可通過(guò)溫度控制來(lái)調(diào)節(jié)。因此溫度應(yīng)力一般不包括此項(xiàng)。日照受多種因素影響，使橋面與內(nèi)部因?qū)α骱蜔醾鲗?dǎo)和熱傳導(dǎo)方式形成不均勻分布，即產(chǎn)生結(jié)構(gòu)的溫度場(chǎng)。溫度場(chǎng)的確定是結(jié)構(gòu)溫度效應(yīng)的關(guān)鍵。橋梁設(shè)計(jì)中通常分溫度沿梁高線性變化和非線性變化。在線性溫差變化情況下，梁式結(jié)構(gòu)將產(chǎn)生撓曲變形，且梁再變形后仍然服從平截面假定。因此，在靜定梁式結(jié)構(gòu)中，線性變化的溫度梯度只引起結(jié)構(gòu)的位移而不產(chǎn)生次內(nèi)力，在連續(xù)梁結(jié)構(gòu)中，它不但引起結(jié)構(gòu)的位移，且由于多余約束的影響，從而產(chǎn)生結(jié)構(gòu)溫度次內(nèi)力，線性溫度梯度下梁的撓曲變形時(shí)與平截面假定一致，縱向纖維幾乎不受約束，因而溫度次應(yīng)力很小，可忽略不計(jì)。而線性變化以外的都屬于非線性溫度梯度形式。再此類非線性溫差分布的情況下，即使靜定結(jié)構(gòu)因要服從平截面假定，導(dǎo)致縱向纖維的伸縮受到約束，從而產(chǎn)生縱向約束應(yīng)力。這部分在截面上自相平衡的約束應(yīng)力稱為溫度自應(yīng)力。而在超靜定梁式結(jié)構(gòu)中除了溫度字應(yīng)力外，還有多余約束產(chǎn)生的次應(yīng)力。溫度應(yīng)力對(duì)預(yù)應(yīng)力混凝土梁橋的危害在近年來(lái)越來(lái)越受到重視。理論分析和實(shí)驗(yàn)研究證明溫度應(yīng)力對(duì)超靜定結(jié)構(gòu)中，溫度應(yīng)力可以達(dá)到甚至超出活載應(yīng)力，已被認(rèn)為是預(yù)應(yīng)力混凝土連續(xù)梁產(chǎn)生裂縫的主要原因。⑴基本結(jié)構(gòu)溫度自應(yīng)力的計(jì)算上面提到，當(dāng)采用非線性溫度梯度時(shí)，即使靜定結(jié)構(gòu)也會(huì)產(chǎn)生自應(yīng)力。對(duì)于連續(xù)梁結(jié)構(gòu)，基本結(jié)構(gòu)為靜定結(jié)構(gòu)，因而亦存在溫度自應(yīng)力。設(shè)溫度梯度沿梁高按任意曲線T（y）分布，取一梁段，當(dāng)縱向纖維不受約束，能自由伸縮沿梁高各點(diǎn)自由變形為：ε（y）=αT（y）(5-1)式中：α——材料的線膨脹系數(shù)。但因梁的變形必須服從平截面假定，所以截面實(shí)際變形后，位置函數(shù)為：εa（y）=ε0+χy(5-2)式中：ε0——沿梁高y=0處的變形值；χ——單元梁段撓曲的曲率。由縱向纖維約束而產(chǎn)生的應(yīng)變?yōu)椋?5-3)由上式產(chǎn)生的應(yīng)力稱為溫度次應(yīng)力，其值為：（5-4）由于在單元梁段上無(wú)外荷載作用，因此自應(yīng)力在截面上是自相平衡的應(yīng)力，可利用截面上應(yīng)力總和為零和對(duì)截面重心軸處力矩為零的條件，求出與值。（5-5）（5-6）將求得的與值代入式（5-4）即可求得溫度自應(yīng)力。⑵連續(xù)梁溫度次內(nèi)力及溫度次應(yīng)力計(jì)算在上式(5-6)中，求的χ值表示非線性溫度梯度變化時(shí)單元梁段產(chǎn)生的撓曲變形的曲率。在連續(xù)梁中，這部分變形會(huì)引起次內(nèi)力，可用力法求解，亦可采用有限元法求解。通過(guò)分析分析可知：溫度梯度與溫度附加力的計(jì)算有很大關(guān)系。如果溫度梯度曲線選用不當(dāng)，即使增大溫度設(shè)計(jì)值，亦不能提高結(jié)構(gòu)的抗裂性。因此，需今后進(jìn)一步通過(guò)大量的研究與分析，找出符合我國(guó)實(shí)際情況的溫度梯度曲線。⑶我國(guó)公路橋梁設(shè)計(jì)規(guī)范中溫度應(yīng)力計(jì)算公式我國(guó)《公路混凝土及預(yù)應(yīng)力混凝土橋梁設(shè)計(jì)規(guī)范》（JTJ023-85）中規(guī)定：混凝土T形截面連續(xù)梁由于日照引起橋面板與其他部分的溫度差，從而產(chǎn)生內(nèi)力。在缺乏實(shí)測(cè)資料時(shí)，可假定溫度差為5°C，并在橋面板均勻分布。因此，我國(guó)公路橋梁設(shè)計(jì)規(guī)范的溫度梯度曲線，亦屬非線性分布。溫度自應(yīng)力的計(jì)算公式為：==(5-7)(5-8)式中：——橋面板重心到截面重心軸的距離；——橋面板的橫截面面積；——梁的橫截面全面積；——截面重心到梁底的距離；——截面繞重心軸的慣性矩；——截面繞梁底的慣性矩。因此(5-9)(5-10)令：則上式可表達(dá)為：(5-11)溫度次應(yīng)力為：(5-12)連續(xù)梁內(nèi)總溫度應(yīng)力為：(5-13)2.溫度力對(duì)結(jié)構(gòu)內(nèi)力的影響在本設(shè)計(jì)中，還未布置預(yù)應(yīng)力筋時(shí)，即估索階段和在完全成橋計(jì)算階段考慮頂板升溫5℃一種溫度力，同時(shí)升溫10℃這兩種溫度力對(duì)橋梁結(jié)構(gòu)的影響。兩種溫度力產(chǎn)生的溫度應(yīng)力由PRBP程序計(jì)算得到，分別于表1~2所示，圖5.1～圖5.4給出了兩種溫度力產(chǎn)生的結(jié)構(gòu)內(nèi)力圖，由內(nèi)力圖可知，頂板升溫5℃產(chǎn)生的結(jié)構(gòu)內(nèi)力比頂板升溫10℃產(chǎn)生的結(jié)構(gòu)內(nèi)力大。在本設(shè)計(jì)中選用變高度箱梁，梁體整體升溫、整體降溫結(jié)構(gòu)會(huì)產(chǎn)生內(nèi)力，但產(chǎn)生內(nèi)力值較小；若為等高度梁，梁體同時(shí)升溫、同時(shí)降溫結(jié)構(gòu)將不會(huì)產(chǎn)生內(nèi)力。表5-1頂板升溫5℃產(chǎn)生的結(jié)構(gòu)內(nèi)力截面號(hào)剪力（t)彎矩（t·m))截面號(hào)剪力（t)彎矩（t·m))1004401332.8999219.2204501332.8999319.2211.5324601332.8999419.2254.7774701332.8999519.22112.43664801332.8999619.22170.09664901332.8999719.22227.75665001332.8999819.22285.41555101332.8999919.22362.29555201332.89991019.2243989991119.22516.05445401332.89991219.22592.93445501332.89991319.22669.81335601332.89991419.22746.69335701332.89991519.22813.96225801332.89991619.22881.23225901332.89991719.22948.50226001332.89991819.221015.77716101332.89991919.221083.044162-19.221313.67792019.221140.700163-19.221275.23392119.221198.36664-19.221256.01192219.221256.02265-19.221198.3662319.221275.24466-19.221140.72419.221313.68867-19.221083.04412519.221332.968-19.221015.77712601332.969-19.22948.50112701332.970-19.22881.23222801332.971-19.22813.96222901332.899972-19.22746.69333001332.899973-19.22669.81333101332.899974-19.22592.93333201332.899975-19.22516.05443301332.899976-19.22439899977-19.22362.29553501332.899978-19.22285.41553601332.899979-19.22227.75663701332.899980-19.22170.09663801332.899981-19.22112.43663901332.899982-19.2254.7774001332.899983-19.2211.5324101332.899984-19.2204201332.899985004301332.8999圖5-1第一組溫度力產(chǎn)生的剪力圖圖5-2第一組溫度力產(chǎn)生的彎矩圖表5-2同時(shí)升溫10℃產(chǎn)生的結(jié)構(gòu)內(nèi)力截面號(hào)剪力（t)彎矩（t·m))截面號(hào)剪力（t)彎矩（t·m))1004402260.8883232.60104502260.8883332.60119.5614602260.8883432.60192.9134702260.8883532.601190.71664802260.8883632.601288.51994902260.8883732.601386.32225002260.8883832.601484.12665102260.8883932.601614.535202260.88831032.601744.93445302260.88831132.60
