【摘要】:本項(xiàng)論文研究通過對(duì)國(guó)內(nèi)外關(guān)于長(zhǎng)大下坡交通安全的研究成果的分析、對(duì)比,找出長(zhǎng)大下坡路段共有的安全問題,并提出治理方案,,用以指導(dǎo)山區(qū)高速公路線形設(shè)計(jì),以盡可能避免其通車后因長(zhǎng)大下坡導(dǎo)致的交通事故。同時(shí),借鑒國(guó)內(nèi)外關(guān)于高速公路隧道口線形安全研究成果,提出了公路隧道部分相關(guān)設(shè)計(jì)建議指標(biāo),以增加速公路隧道行車安全性。 本論文研究了下坡線形安全設(shè)計(jì)方法,根據(jù)坡度嚴(yán)重性分析系統(tǒng)(Grade SeverityRating System)模型的修正結(jié)果、散熱試驗(yàn)的分析結(jié)果和制動(dòng)器溫度預(yù)測(cè)模型試驗(yàn)結(jié)果以及車輛動(dòng)力學(xué)分析結(jié)論,提出山嶺重丘區(qū)高速公路長(zhǎng)大下坡路段坡度及坡長(zhǎng)組合指標(biāo),包括:平均縱坡和總坡長(zhǎng)的總體控制、縱坡的坡度坡長(zhǎng)組合、緩坡坡度坡長(zhǎng)、反坡設(shè)置等,進(jìn)而對(duì)平縱線形組合提出了安全設(shè)計(jì)建議。其目的與意義重點(diǎn)在于: (1)通過連續(xù)下坡路段不同載重、車速條件下的大貨車輪轂溫度實(shí)時(shí)測(cè)量試驗(yàn),對(duì)美國(guó)的GSRS制動(dòng)器溫度預(yù)測(cè)模型進(jìn)行了檢驗(yàn)和修正; (2)建立新的制動(dòng)器溫度預(yù)測(cè)模型并提出縱坡優(yōu)化設(shè)計(jì)指標(biāo); (3)提高山區(qū)高速公路長(zhǎng)大下坡路段的交通安全性。
[Abstract]:Based on the analysis and comparison of the research results on the traffic safety of long - up and lower slope , this paper tries to find out the common security problems in the growth and lower slope , and put forward the control scheme to guide the linear design of the highway tunnel , so as to avoid the traffic accidents caused by the growth and descent of the highway tunnel . At the same time , the related design suggestion index of the highway tunnel part is put forward to increase the safety of the highway tunnel . Based on the results of the analysis of Grade SeverityRating System ( Grade SeverityRating System ) , the results of the analysis of the heat dissipation test and the results of the brake temperature prediction model test and the conclusion of the vehicle dynamics analysis , the paper puts forward the combination index of the slope and the slope length of the growth and lower slope of the expressway in the mountain range , including the overall control of the average longitudinal slope and the total slope length , the slope length combination of the longitudinal slope , the slope length of the gentle slope and the slope setting , etc . , and then puts forward the safety design suggestion for the flat longitudinal linear combination . The purpose and significance of the design are as follows : ( 1 ) The GSRS brake temperature prediction model of the United States is tested and corrected by the real - time measurement test of the wheel hub temperature under different load and vehicle speed conditions of the continuous downhill section . ( 2 ) establishing a new brake temperature prediction model and proposing a longitudinal slope optimization design index ; and ( 3 ) improving the traffic safety of the growing lower slope section of the mountain highway .
