中文摘要 | 潛盾施工所引致之地盤沈陷問題為都市土木中隧道工程之重要課題,而由於潛盾 機推進隆起、開挖解壓所衍生之地盤漏失及孔隙水壓變化正造成地盤沈陷之主因。本研究在 潛盾機通過電子式水壓計之監測斷面前後實施密集記讀,以瞭解潛盾施工引致孔隙水壓之變 化情形。文中亦建立模擬潛盾施工之數值分析架構,利用現地監測資料驗證此分析架構之適 用性,以探討推力與超額孔隙水壓增量及壓密沈陷間之關係。 |
英文摘要 | Ground settlement induced by shield tunneling is an important issue in the tunnel construction in urban area. The ground loss and pore pressure change induced by the advance of shield machine and the unloading of excavation are the major causes for the ground settlement. To understand the mechanism of pore pressure evolution intense measurements of the pore pressure transducers are taken before and after shield machine passing through the monitoring section. An analytical model is established and verified by comparisons with the field data. Numerical analysis is performed to investigate the relationship between thrusts, excess pore pressure increments, and consolidation settlements. |
