【摘要】：預(yù)加固技術(shù)作為一種被廣泛采用的路基與邊坡加固方法，其適宜性自然而然的受到各方面極大的關(guān)注。對(duì)于工程技術(shù)人員而言，選取適宜的預(yù)加固方法便可以達(dá)到事半功倍的效果，就能夠保證路基與邊坡的安全；對(duì)于預(yù)加固決策者或管理者而言，選取適宜的預(yù)加固方法就意味著能夠保證公路正常的運(yùn)營。此外，在實(shí)際預(yù)加固決策過程中，由于預(yù)加固決策者常常受到眾多因素的影響和干擾，往往不能獲得較為符合實(shí)際的預(yù)加固決策結(jié)果，不僅錯(cuò)過了路基與邊坡預(yù)加固的最佳時(shí)機(jī)，而且還造成了資金的極大浪費(fèi)�；诖�，開展路基與邊坡預(yù)加固方法適宜性評(píng)價(jià)和預(yù)加固決策方法研究具有較大的現(xiàn)實(shí)意義。 本文以預(yù)加固工程中的公路路基與邊坡為研究對(duì)象，，結(jié)合預(yù)加固工程實(shí)際情況，對(duì)典型公路路基與邊坡預(yù)加固方法的適宜性及預(yù)加固決策方法進(jìn)行了分析和研究，得到的主要成果如下： ①結(jié)合現(xiàn)行規(guī)范、工程實(shí)際及預(yù)加固方法自身特點(diǎn)，確立了公路路基與邊坡預(yù)加固方法適宜性評(píng)價(jià)指標(biāo)。 ②在公路路基與邊坡預(yù)加固方法適宜性評(píng)價(jià)過程中，引入了模糊層次分析法，建立了由4個(gè)一級(jí)評(píng)價(jià)指標(biāo)和13個(gè)二級(jí)評(píng)價(jià)指標(biāo)組成的公路路基與邊坡預(yù)加固方法適宜性評(píng)價(jià)體系。 ③針對(duì)公路路基與邊坡預(yù)加固對(duì)公路交通通行條件的影響機(jī)制，構(gòu)建了以預(yù)加固占用的車道數(shù)、預(yù)加固工點(diǎn)處平均車速、預(yù)加固的工期為指標(biāo)的評(píng)價(jià)體系。 ④對(duì)公路典型路基與邊坡預(yù)加固方法（減載和反壓技術(shù)、支擋結(jié)構(gòu)措施、灌注漿措施）的適宜性進(jìn)行了分析和評(píng)價(jià)。 ⑤提出了基于價(jià)值工程理論的公路路基與邊坡預(yù)加固決策方法，建立了路基與邊坡預(yù)加固決策模型。
[Abstract]:As a widely used method of embankment and slope reinforcement, the suitability of pre-reinforcement technology has been paid great attention to. For engineers and technicians, the selection of appropriate pre-reinforcement method can achieve twice the result with half the effort, can ensure the safety of subgrade and slope, and for the decision maker or manager of pre-reinforcement, Choosing appropriate pre-reinforcement means that it can guarantee the normal operation of highway. In addition, in the actual pre-reinforcement decision-making process, because the pre-reinforcement decision makers are often affected and interfered by many factors, they are often unable to obtain more realistic pre-reinforcement decision results. It not only missed the best time of embankment and slope pre-reinforcement, but also caused a great waste of funds. Based on this, it is of great practical significance to evaluate the suitability of roadbed and slope pre-reinforcement method and to study the pre-reinforcement decision method. Taking highway subgrade and slope in pre-reinforcement engineering as the research object and combining with the actual situation of pre-strengthening project, this paper analyzes and studies the suitability and decision-making method of pre-reinforcement of typical highway roadbed and slope. The main results were as follows: The main results are as follows: (1) based on the current code, engineering practice and characteristics of pre-reinforcement method, the suitability evaluation index of highway roadbed and slope pre-reinforcement method is established. (2) in the process of evaluating the suitability of highway roadbed and slope pre-reinforcement method, the fuzzy analytic hierarchy process is introduced. The suitability evaluation system of highway roadbed and slope pre-reinforcement method is established, which consists of 4 first-grade evaluation indexes and 13 second-grade evaluation indexes. (3) aiming at the influence mechanism of highway roadbed and slope pre-reinforcement on highway traffic conditions, an evaluation system based on the number of driveway occupied by pre-reinforcement, the average speed at pre-strengthened work point and the time limit of pre-reinforcement is constructed. (4) the suitability of typical roadbed and slope pre-reinforcement methods (load reduction and backpressure technology, retaining structure measures, grouting measures) is analyzed and evaluated. 5. The decision method of highway roadbed and slope pre-reinforcement based on value engineering theory is put forward, and the decision model of roadbed and slope pre-reinforcement is established.
