【摘要】：鑒于目前公路隧道健康評(píng)價(jià)在指標(biāo)權(quán)重確定、評(píng)價(jià)理論等方面存在的不足,論文對(duì)評(píng)價(jià)指標(biāo)體系、指標(biāo)判定標(biāo)準(zhǔn)及其無(wú)量綱化、指標(biāo)權(quán)重的確定方法、隧道襯砌結(jié)構(gòu)健康評(píng)價(jià)理論進(jìn)行了深入研究。主要研究?jī)?nèi)容如下:1通過(guò)對(duì)六河高速和宜河高速公路隧道現(xiàn)場(chǎng)檢測(cè)數(shù)據(jù)的統(tǒng)計(jì)分析,掌握了襯砌裂縫、滲漏水、襯砌厚度、襯砌背后空洞的分布情況,并分析其成因。2根據(jù)評(píng)價(jià)指標(biāo)的選取原則,詳細(xì)分析了公路隧道襯砌結(jié)構(gòu)破損形態(tài)及其健康影響因素,確定了襯砌結(jié)構(gòu)健康評(píng)價(jià)指標(biāo),建立了公路隧道襯砌結(jié)構(gòu)健康狀況評(píng)價(jià)指標(biāo)體系。3分析國(guó)內(nèi)外現(xiàn)有隧道健康等級(jí)劃分方法,結(jié)合我國(guó)隧道工程的特點(diǎn),將公路隧道襯砌結(jié)構(gòu)健康等級(jí)劃分為五級(jí)。在已有研究成果的基礎(chǔ)上,給出了各評(píng)價(jià)指標(biāo)的判定標(biāo)準(zhǔn),并建立了指標(biāo)的無(wú)量綱化公式。4為克服層次分析法的不足及反映各專家的評(píng)判水平,利用模糊層次分析法和熵值理論綜合確定指標(biāo)權(quán)重,提高了權(quán)重系數(shù)的精度。5分析現(xiàn)有評(píng)價(jià)方法的優(yōu)缺點(diǎn),提出了基于可變模糊集理論的公路隧道襯砌結(jié)構(gòu)健康狀況評(píng)價(jià)方法。研究結(jié)果表明,可變模糊綜合評(píng)價(jià)模型在公路隧道襯砌結(jié)構(gòu)健康評(píng)價(jià)中具有較好的適用性,利用模型的可變性對(duì)級(jí)別特征值的穩(wěn)定性進(jìn)行分析,最終綜合不同模型的評(píng)價(jià)結(jié)果以確定襯砌結(jié)構(gòu)健康等級(jí),提高了評(píng)價(jià)結(jié)果的可靠性。
[Abstract]:In view of the shortcomings of the current highway tunnel health evaluation in the determination of index weight and evaluation theory, the paper gives an analysis of the evaluation index system, criteria and dimensionless criteria, and the method of determining index weight. The health evaluation theory of tunnel lining structure is studied in depth. The main contents of the study are as follows: 1 through the statistical analysis of the field detection data of Liuhe Expressway and Yihe Expressway Tunnel, the lining cracks, leakage water, lining thickness have been mastered. The distribution of the cavity behind the lining is analyzed. 2. According to the selection principle of the evaluation index, the damaged form of the lining structure of highway tunnel and its health influencing factors are analyzed in detail, and the health evaluation index of the lining structure is determined. The evaluation index system of health status of highway tunnel lining structure is established. 3. Analysis of existing methods of tunnel health classification at home and abroad, combined with the characteristics of tunnel engineering in China. The health grade of highway tunnel lining structure is divided into five grades. On the basis of the existing research results, the evaluation criteria of each evaluation index are given. In order to overcome the deficiency of AHP and reflect the evaluation level of experts, the index weight is determined by fuzzy analytic hierarchy process (FAHP) and entropy theory. The accuracy of weight coefficient is improved and the advantages and disadvantages of existing evaluation methods are analyzed. Based on the theory of variable fuzzy set, a method for evaluating the health status of highway tunnel lining structure is proposed. The results show that, The variable fuzzy comprehensive evaluation model has good applicability in the health evaluation of highway tunnel lining structure. The stability of the class eigenvalue is analyzed by using the variability of the model. Finally, the evaluation results of different models are synthesized to determine the health grade of lining structure, and the reliability of the evaluation results is improved.
