Abstract:	摘要：擠壓砂樁為軟弱地盤常用之地盤改良工法，然施打過程中將引致地盤振動。本研究針對台中火力發電廠灰塘區煤灰回填地盤所進行之擠壓砂樁工程，量測施打時所引致之地盤振動，探討其最大地表速度、頻率特性及隨距離衰減之趨勢等。現地量測結果顯示，在施打擠壓砂樁之貫入、拉拔及擠壓等三階段中，以擠壓至接近地表時所造成之地盤振動量最大，且其顯著頻率恰為振動打樁機之運轉頻率，而擠壓煤灰層時之地盤振動較擠壓原始土層時易於衰減；若將量測數據與各國振動規範中之容許準則比較，可知施打擠壓砂樁之地盤振動對於20 m外之結構幾無影響。出版者：台灣: 中國土木水利工程學會出版日期： 2014-12-01 出處：中國土木水利工程學刊, 2014-12, Vol.26 (4), p.323-334 資源來源：華藝CEPS中文電子期刊服務識別號： ISSN: 1015-5856 識別號： DOI: 10.6652/JoCICHE.201412_26(4).0005
