［摘要］城市軌道交通及其他地下工程的建設(shè)規(guī)模的逐漸擴(kuò)大，地連墻由于其優(yōu)越性已逐漸成為主要的圍護(hù)結(jié)構(gòu)。受到高壓電纜等綜合管線(xiàn)的影響，局部地連墻無(wú)法采用垂直成槽技術(shù)，需根據(jù)場(chǎng)地情況選擇特殊施工工藝。以天津在建最大的地鐵換乘站為背景，研究了在220kV電纜影響下的地連墻施工工藝，在保證工程質(zhì)量的基礎(chǔ)上完成工期節(jié)點(diǎn)目標(biāo)。對(duì)施工工藝及時(shí)進(jìn)行總結(jié)，提出進(jìn)一步改進(jìn)措施，可為類(lèi)似工程提供借鑒。

Abstract: The construction of urban rail traffic and other underground engineering scale are expanding gradually, even becomes the primary wall retaining structure. Under the influence of high voltage cable and so on comprehensive pipeline, locally in even the wall is vertical slot technology, special construction technology to choose according to site situation. In tianjin's largest metro transfer station under construction background, the research on 220 kv cable under the influence of the construction process, the wall to ensure the engineering quality target finish time limit for a project on the basis of nodes. A summary of the construction process in a timely manner, improvement measures are put forward, and can provide reference for similar projects.
