中文摘要 | 臺灣地處太平洋板塊與歐亞大陸板塊交界,地質構造發達,多斷層、軟弱岩層、 節理與剪裂帶等地質弱帶及豐富之地下水。這些地質弱帶及地下水除了造成隧道 施工之障礙,日後方可能導致隧道襯砌之破壞,進而影響營運安全。同時,由於 臺灣本島多山,為了交通、水利及軍事等用途,修建了不少隧道,部分隧道已屆 使用年限,襯砌本身材質劣化,需要檢測、維修、補強。本文以實例介紹以透地 雷達法,探查老舊隧道襯砌之完整性及其背後空洞之分佈,並與鑽心取樣比對, 以探討其可行性及限制。另外亦將介紹影像掃描系統在襯砌表面裂縫及滲水情形 調查之應用。 |
英文摘要 | Taiwan Island is situated on the boundary between the Pacific Plate and the Asia Continental plate. Geological structures such as faults, weak strata, joints and fractured zones and surge of ground water are frequently encountered in Taiwan island. These geological conditions are quite detrimental for tunnelling construction and generally result in the destruction of concrete lining after tunnelling completion. Many tunnels had been made in the mountain areas of Taiwan for transportation, hydropower and military purposes. The linings of these tunnels are damaged gradually after operating for many years and need to be inspected, refurbished and reinforces. Examples are introduced here to discuss the application of Ground penetrating Radar and Visual scanning methods in the tunnel inspection for the linging condition and for the distribution of cave behind linging. |
