【摘要】：本案例場(chǎng)地屬于寧波市巖層地層區(qū),主要為白堊系紫紅色粉砂巖和局部分布的燕山晚期噴出巖玄武巖,第四紀(jì)地層發(fā)育厚度較大,且層位較穩(wěn)定,厚度約55-100m,從中更新世至全新世地層發(fā)育齊全。在對(duì)寧波軌道交通盾構(gòu)隧道工程進(jìn)行全面建設(shè)的過程中,該隧道的地質(zhì)結(jié)構(gòu)較為復(fù)雜,且自然環(huán)境十分惡劣,這些因素的存在造成了該項(xiàng)目在實(shí)施過程中具有極大的風(fēng)險(xiǎn)。地鐵盾構(gòu)隧道工程具有社會(huì)影響面廣、投資款項(xiàng)巨大、建設(shè)工程體量龐大、工程工序繁復(fù)、且風(fēng)險(xiǎn)因素多,一旦遭遇險(xiǎn)情,將會(huì)產(chǎn)生較為惡劣性的影響。因此,需要在隧道工程施工之前進(jìn)行風(fēng)險(xiǎn)的預(yù)判、分析及準(zhǔn)備應(yīng)對(duì)措施,為后續(xù)工程施工打下堅(jiān)定的基礎(chǔ)。本文在案例分析的過程中,對(duì)寧波軌道交通矩形盾構(gòu)隧道在施工過程中的風(fēng)險(xiǎn)控制具有深遠(yuǎn)的意義。本文在具體分析研究過程中,主要的內(nèi)容從以下幾個(gè)方面進(jìn)行展開,即:(1)根據(jù)國(guó)內(nèi)外近幾年風(fēng)險(xiǎn)管理的基本研究現(xiàn)狀進(jìn)行總結(jié),對(duì)于盾構(gòu)隧道工程風(fēng)控這一方面所存在的問題進(jìn)行歸納與梳理。在此基礎(chǔ)上,結(jié)合風(fēng)險(xiǎn)分析理論,對(duì)具體案例中的風(fēng)險(xiǎn)控制與評(píng)估提出可行性的方案;(2)通過工程風(fēng)險(xiǎn)的基本定義,對(duì)基本的風(fēng)險(xiǎn)類與特征進(jìn)行簡(jiǎn)要的介紹,從具體工程相關(guān)的風(fēng)險(xiǎn)管理方面對(duì)相關(guān)的理論進(jìn)行深入化的論述與分析。(3)建立矩形盾構(gòu)隧道施工風(fēng)險(xiǎn)模糊綜合評(píng)價(jià)體系,以寧波市軌道交通3號(hào)線一期地下土建工程TJ3111標(biāo)段及寧波市軌道交通3號(hào)線一期工程出入段線矩形盾構(gòu)施工(黃家村站、陳婆渡站~黃家村站區(qū)間、陳婆渡站、姜山出入段線明挖和矩形盾構(gòu)區(qū)間,整個(gè)隧道一共是2站2區(qū)間)工程為具體的實(shí)例,通過層次分析方式對(duì)其中相關(guān)的風(fēng)險(xiǎn)因素進(jìn)行全面性的分析與探究。在此基礎(chǔ)上,結(jié)合模糊評(píng)價(jià)分析方式,提出了針對(duì)性的技術(shù)措施。(4)在風(fēng)險(xiǎn)評(píng)價(jià)基礎(chǔ)上,針對(duì)本工程盾構(gòu)進(jìn)行了矩形盾構(gòu)和圓形盾構(gòu)的對(duì)比分析,同時(shí)進(jìn)行了進(jìn)出洞施工風(fēng)險(xiǎn)、穿越特殊地段、管片拼裝施工風(fēng)險(xiǎn)的技術(shù)措施分析,提出了寧波地鐵矩形盾構(gòu)隧道施工的質(zhì)量保證措施。
[Abstract]:The site of this case belongs to the lithostratigraphic area of Ningbo, mainly Cretaceous purplish red siltstone and locally distributed late Yanshanian exhalation basalt. The Quaternary strata are relatively thick and stable, and the thickness is about 55-100 m. From the Middle Pleistocene to the Holocene, the strata are well developed. In the process of overall construction of shield tunneling project of Ningbo rail transit, the geological structure of the tunnel is more complicated and the natural environment is very bad. The existence of these factors causes the great risk in the implementation of the project. The shield tunnel project of subway has a wide range of social influence, huge investment, huge volume of construction engineering, complicated engineering process and many risk factors. Once encountered with dangerous situation, it will have a more bad effect. Therefore, it is necessary to prejudge, analyze and prepare the risk before the tunnel construction, so as to lay a firm foundation for the subsequent construction. In the course of case analysis, this paper has profound significance for risk control of Ningbo rail transit rectangular shield tunnel in construction process. In the process of concrete analysis and research, the main contents are as follows: (1) according to the basic research situation of risk management at home and abroad in recent years, The existing problems in wind control of shield tunnel engineering are summarized and sorted out. On this basis, combining with the theory of risk analysis, the feasibility of risk control and evaluation in specific cases is put forward. (2) through the basic definition of engineering risk, the basic risk classes and characteristics are briefly introduced. The related theories are discussed and analyzed from the aspect of risk management related to specific projects. (3) the fuzzy comprehensive evaluation system of construction risk of rectangular shield tunnel is established. The rectangular shield construction of the first phase underground civil engineering of Ningbo Rail Transit Line 3 and the first phase of Ningbo Rail Transit Line 3 is carried out by rectangular shield construction (Huangjiacun Station, Chenpodu Station ~ Huangjiacun Station, Chen Bodu Station, Chenpo Duyu Station, and Huangjiacun Station). The project of line opening excavation and rectangular shield tunneling in Jiang Shan's entrance and exit section, which consists of 2 stations and 2 sections, is a concrete example. The related risk factors are comprehensively analyzed and explored by means of analytic hierarchy process (AHP). On this basis, combined with the fuzzy evaluation and analysis method, put forward targeted technical measures. (4) on the basis of risk assessment, the rectangular shield and circular shield are compared and analyzed. At the same time, the paper analyzes the construction risk of entering and leaving the tunnel, crossing the special section and assembling the segment, and puts forward the quality assurance measures for the construction of Ningbo subway rectangular shield tunnel.
