【摘要】：近年來(lái)我國(guó)地鐵建設(shè)蓬勃發(fā)展,但地鐵隧道的滲漏水問(wèn)題卻屢見(jiàn)不鮮,現(xiàn)有的隧道滲漏水檢測(cè)方法多存在著效率低、成本高等缺點(diǎn)。因此,本文根據(jù)滲漏水后管片物理特性的變化,提出兩種長(zhǎng)期自動(dòng)檢測(cè)隧道滲漏水的新方法:溫度梯度法和電導(dǎo)率法。通過(guò)一系列室內(nèi)試驗(yàn),證明這兩種方法在不同滲漏水下均具有一定可行性。根據(jù)試驗(yàn)結(jié)果設(shè)計(jì)出兩套滲漏水檢測(cè)系統(tǒng),在上海地鐵隧道中進(jìn)行現(xiàn)場(chǎng)檢測(cè),發(fā)現(xiàn)電導(dǎo)率法檢測(cè)滲漏水更加高效、敏感,且價(jià)格低廉,具有良好的應(yīng)用前景。
[Abstract]:In recent years, the subway construction in our country has developed vigorously, but the leakage problem of subway tunnel is not uncommon. Most of the existing tunnel leakage detection methods have the disadvantages of low efficiency, high cost and so on. Therefore, according to the changes of the physical characteristics of pipes after leakage, this paper presents two new methods: temperature gradient method and conductivity method, which can be used to detect tunnel leakage automatically for a long time. Through a series of laboratory tests, it is proved that the two methods are feasible under different seepage conditions. Based on the experimental results, two sets of leakage detection systems were designed and tested in Shanghai subway tunnel. It is found that the conductivity method is more efficient, sensitive and cheap, and has a good application prospect.
