【摘要】：為了避免管線受地鐵施工帶來的影響,許多管線被迫遷移,但在某些情況下管線無法遷移時(shí),必須采取合理的施工措施,保證盾構(gòu)始發(fā)井的施工對(duì)周圍管線的影響降低到最小。文章以西安地鐵3號(hào)線為工程背景,建立了盾構(gòu)始發(fā)井施工過程的FLAC模擬計(jì)算模型,制定了管線的監(jiān)測(cè)方案,分析了通-胡區(qū)間盾構(gòu)始發(fā)井施工對(duì)周圍排水管線及給水管線的變形影響規(guī)律,提出了合理的管線變形保護(hù)措施。研究表明,盾構(gòu)始發(fā)井施工時(shí),對(duì)周圍環(huán)境的影響大小是不一樣的,隨著距盾構(gòu)始發(fā)井距離的增大,影響程度逐漸減小。實(shí)踐表明,計(jì)算結(jié)果和監(jiān)測(cè)結(jié)果基本一致,提出的盾構(gòu)始發(fā)井施工方案可有效地減小施工對(duì)周圍管線產(chǎn)生的變形影響。
[Abstract]:In order to avoid the influence of subway construction, many pipelines are forced to migrate, but in some cases, when the pipeline can not be transferred, reasonable construction measures must be taken to ensure that the influence of shield initiation well construction on the surrounding pipeline is minimized. Based on Xi'an Metro Line 3, this paper establishes the FLAC simulation calculation model of shield initiation well construction process, formulates the monitoring scheme of pipeline, analyzes the influence of shield initiation well construction on the deformation of surrounding drainage pipeline and water supply pipeline, and puts forward reasonable pipeline deformation protection measures. The results show that the influence on the surrounding environment is different during the construction of the shield initiation well, and the influence degree decreases with the increase of the distance from the shield initiation well. The practice shows that the calculated results are basically consistent with the monitoring results, and the proposed shield initiation well construction scheme can effectively reduce the deformation influence of the construction on the surrounding pipeline.
