頂管事故一旦發生，將影響施(shi)(shi)工(gong)(gong)(gong)進度、居民生活(huo)和出行，甚至造成(cheng)(cheng)人員傷(shang)亡(wang)。然(ran)而，大多數頂管事故都是由于施(shi)(shi)工(gong)(gong)(gong)前(qian)的(de)(de)準(zhun)備工(gong)(gong)(gong)作和安全防護(hu)措施(shi)(shi)不到位造成(cheng)(cheng)的(de)(de)。因此，頂管施(shi)(shi)工(gong)(gong)(gong)的(de)(de)一個重要(yao)(yao)問(wen)題是地(di)層適應(ying)性。根據不同土(tu)質、不同施(shi)(shi)工(gong)(gong)(gong)條(tiao)件、不同要(yao)(yao)求(qiu)，選(xuan)擇合適的(de)(de)頂管施(shi)(shi)工(gong)(gong)(gong)方(fang)法和合理的(de)(de)頂管參數，才(cai)能達到事半功(gong)倍的(de)(de)效(xiao)果。否則(ze)，可(ke)能會給頂管施(shi)(shi)工(gong)(gong)(gong)帶來(lai)困難(nan)，甚至導致頂管失敗(bai)，給工(gong)(gong)(gong)程造成(cheng)(cheng)巨(ju)大損失。頂管施(shi)(shi)工(gong)(gong)(gong)過程中(zhong)，沿途土(tu)層變(bian)化(hua)頻繁，所以(yi)在頂管施(shi)(shi)工(gong)(gong)(gong)前(qian)了解土(tu)層變(bian)化(hua)是很有(you)必要(yao)(yao)的(de)(de)。對于需要(yao)(yao)回填的(de)(de)地(di)段要(yao)(yao)通(tong)過提前(qian)加(jia)固，否則(ze)頂管施(shi)(shi)工(gong)(gong)(gong)后地(di)表可(ke)能會過度下(xia)沉。臨時水準(zhun)點應(ying)設置在交通(tong)要(yao)(yao)道(dao)、挖填方(fang)范(fan)圍以(yi)外(wai)。湖里區非開挖頂管施(shi)(shi)工(gong)(gong)(gong)公司
