摘要

本文整理中和地區某一潛盾隧道工程於粘土層中施行高壓噴射灌漿環試灌之案例探討單管、雙重管及三重管灌漿施工過程引致之地層變位特性包括隆起、沉陷、側向變位等。由試灌結果顯示高壓噴射灌漿所引起之地層位移受地層條件、灌漿柱體配置、施工方法及其所採用之工作參數、灌漿順序及施工技術、品質等影響，無一定之模式，很難以學理方法或經驗作定量之預測。

A test grouting work was carried out in the clay layer in Chungho area where a shield tunnelling work will be constructed. The single tube, double tube and triple tube system were used in this jet grouting test program and the ground movement caused by jet grouting was monitored. The result of this test grouting suggested that the ground movement ca used by jet grouting might be affected by soil condition, layout of the grouting columns, grouting methods, grouting parameters, grouting sequence and construction quality. There is no certain model can be used to predict the ground movement ca use by jet grouting.
