【摘要】：研究目的:鑒于我國(guó)鐵路特別是艱險(xiǎn)山區(qū)鐵路的大量修建,建設(shè)施工的風(fēng)險(xiǎn)也增大,而控制風(fēng)險(xiǎn)的源頭在于設(shè)計(jì)。鐵路設(shè)計(jì)經(jīng)過(guò)多年的發(fā)展,更加注重工程的安全性、可靠性、低風(fēng)險(xiǎn)性、經(jīng)濟(jì)性。本文研究了玉溪至磨憨鐵路前期工作選線設(shè)計(jì),提出了各設(shè)計(jì)階段的選線思路。研究結(jié)論:(1)玉溪至磨憨鐵路地形起伏大,地質(zhì)條件復(fù)雜,風(fēng)險(xiǎn)較高,通過(guò)大量的方案綜合比選,使線路從熱泉低溫帶穿過(guò),活動(dòng)斷裂對(duì)工程的影響小,隧道風(fēng)險(xiǎn)大大降低,為以后的設(shè)計(jì)打下了堅(jiān)實(shí)的基礎(chǔ);(2)不同的鐵路項(xiàng)目,其選線的風(fēng)險(xiǎn)是不同的,應(yīng)根據(jù)項(xiàng)目具體分析風(fēng)險(xiǎn)選線的原則,從設(shè)計(jì)過(guò)程分析,地質(zhì)與風(fēng)險(xiǎn)綜合選線在預(yù)可研階段以宏觀分析判斷為主,應(yīng)以區(qū)域地質(zhì)資料結(jié)合現(xiàn)場(chǎng)調(diào)研情況擬定重大風(fēng)險(xiǎn)選線原則,從而指導(dǎo)選線設(shè)計(jì),可研階段要進(jìn)一步查明地質(zhì)條件并對(duì)重大地質(zhì)風(fēng)險(xiǎn)進(jìn)行驗(yàn)證,有必要進(jìn)行地質(zhì)專題研究,初步設(shè)計(jì)和施工圖階段要落實(shí)工程措施;(3)本文的研究可對(duì)其他高風(fēng)險(xiǎn)鐵路工程選線設(shè)計(jì)提供一定的借鑒意義。
[Abstract]:Aim: in view of the large number of railway construction in our country, especially in difficult mountain area, the risk of construction also increases, and the source of risk control lies in the design. After years of development, railway design pays more attention to safety, reliability, low risk and economy. In this paper, the route selection design of Yuxi-Mohan railway is studied, and the train of thought for each design stage is put forward. The conclusions are as follows: (1) the Yuxi-Mohan railway has large terrain fluctuation, complex geological conditions and high risk. Through comprehensive selection of a large number of schemes, the line passes through the low temperate zone of the hot spring, and the active faults have little impact on the project. The tunnel risk is greatly reduced, which lays a solid foundation for the future design. (2) the risk of route selection is different in different railway projects. According to the principle of risk selection, according to the principle of concrete analysis of the project, from the analysis of design process, the comprehensive route selection of geology and risk is mainly based on macro-analysis and judgment in the stage of pre-research. The principle of major risk line selection should be drawn up based on regional geological data combined with field investigation, so as to guide the route selection design. At the stage of research, geological conditions should be further identified and major geological risks verified, and it is necessary to carry out special geological studies. Engineering measures should be implemented in the stage of preliminary design and construction drawings; (3) the research in this paper can be used for reference to other high-risk railway projects.
