質(zhì)量等目標(biāo)編制文件。

(2)遵循設(shè)計(jì)文件的原則。在編制方案時(shí)，認(rèn)真閱讀核對(duì)所獲得的設(shè)計(jì)文件資料，

理解設(shè)計(jì)意圖，充分調(diào)查現(xiàn)場情況，嚴(yán)格按設(shè)計(jì)資料和設(shè)計(jì)原則編制方案，滿足設(shè)計(jì)標(biāo)

準(zhǔn)和要求。

(3)全面兌現(xiàn)合同的原則。以一流的技術(shù)、一流的管理、一流的裝備、一流的質(zhì)量，

高起點(diǎn)開局、高標(biāo)準(zhǔn)推進(jìn)、高質(zhì)量完成承建工程。

(4)堅(jiān)持科學(xué)性、先進(jìn)性、經(jīng)濟(jì)性與合理性、實(shí)用性相結(jié)合的原則。采用先進(jìn)的施

2

工技術(shù)、科學(xué)的組織方法，合理的安排順序，推動(dòng)技術(shù)進(jìn)步，實(shí)現(xiàn)經(jīng)濟(jì)效益與社會(huì)效益

的雙豐收。

(5)積極推廣應(yīng)用新技術(shù)、新工藝、新設(shè)備、新材料，采用成熟可靠的方法和工藝，

依靠專業(yè)化、機(jī)械化、信息化，優(yōu)化施工方案，不斷地創(chuàng)新，實(shí)現(xiàn)質(zhì)量目標(biāo)。

(6)連續(xù)梁工程工期緊、質(zhì)量標(biāo)準(zhǔn)高、專業(yè)接口多、相互制約因素多，必須保證足

夠的技術(shù)裝備及人員投入，合理安排施工工序，充分考慮氣候、季節(jié)、交叉施工對(duì)工期

的影響，確保工期。

(7)堅(jiān)持以人為本，安全生產(chǎn)的原則。施工生產(chǎn)活動(dòng)始終把人的健康安全放在首位，

嚴(yán)格執(zhí)行《職業(yè)健康安全管理體系要求及使用指南》GB/T45001-2023，認(rèn)真編制施工

安全技術(shù)方案，加強(qiáng)過程控制，落實(shí)保證措施，保證安全生產(chǎn)投入，實(shí)現(xiàn)安全生產(chǎn)。

(8)堅(jiān)持文明施工、保護(hù)環(huán)境、節(jié)約資源的原則。實(shí)現(xiàn)文明施工，重視環(huán)境保護(hù)，

合理規(guī)劃臨時(shí)用地，節(jié)約原材料消耗，按照國家、中國國家及業(yè)主對(duì)本工程的環(huán)境保護(hù)

要求，精心組織，嚴(yán)格管理，創(chuàng)建安全文明施工標(biāo)準(zhǔn)化工地。

全橋頂板厚30cm，底板厚38~50cm，在梁高變化段范圍內(nèi)按折線變化，邊跨端塊

處底板厚由38cm漸變至50cm；腹板厚30~50cm，按折線變化，邊跨端塊處頂板厚由

30cm漸變至50cm。梁體在支座處設(shè)橫隔板，全聯(lián)共設(shè)4道橫隔板，橫隔板中部設(shè)有孔

洞，以利檢查人員通過。

(3)支座型號(hào)

邊墩支座采用球形鋼支座-Q3000-ZX-0.1g型，固定主墩采用球形鋼支座-Q12500-

GD-0.1g型，活動(dòng)主墩采用球形鋼支座-Q12500-ZX-0.1g型。

(4)梁體混凝土

梁體采用C50混凝土，其技術(shù)條件必須滿足《鐵路混凝土結(jié)構(gòu)耐久性設(shè)計(jì)規(guī)范》

(TB10005--2010)的要求。保護(hù)層厚度按照《鐵路混凝土結(jié)構(gòu)耐久性設(shè)計(jì)規(guī)范》(TB

1000
