近年來，地下岩石隧道工程以及岩石邊坡工程頻傳災害，因此岩石之強度行為的監測及分析，就成了很重要的一環，由於測試現地岩石試體強度之試驗過程複雜，需事先取樣或於現地施作破壞試驗，此試驗過程繁雜，且需要花費較高金額，而若能事先將破壞性試驗與非破壞性試驗兩者之關係求出並且獲得可信賴之成果，則可應用於現地且大幅降低求取現地岩石強度過程之繁瑣及昂貴程度。因此本研究將利用水泥砂漿與混凝土試體模擬岩心取樣所得之完整岩塊試體，並且也利用現地岩心進行試驗，用以作為岩石非破壞性試驗及破壞試驗所得結果之比較，利用岩石史密斯硬度錘之反彈值與點荷重試驗、單軸抗壓試驗所得之參數，以及利用岩石超音波試驗所得到之參數，並將其結果所得到之非破壞性試驗以及破壞性試驗之關係，再與前人研究所得之現地岩心試體試驗結果數據，進行統計分析比較，並驗證其室內試驗結果之關係是否具有可信度，而試驗結果顯示，各試驗間均具有相關性，且所有試驗參數與單壓試驗參數比較後均具有正相關之關聯性。

In recent years, the underground rock tunnel and rock slope happened in disasters. Therefore, the monitoring and analysis of rocks’ strength became an important thing. The process of testing rocks' strength is very complicated because it needs to prepare the specimen first or perform the destructive test in situ. In fact, it takes time and money. If we can get the relationship between non-destructive tests and destructive tests, a reasonable result can be probably obtained. This relationship can let us predict the field rock strength and reduce the cost to get the rock strength. Therefore, this study adopts cement mortar, concrete specimens and the intact rock obtained from drilling boreholes to established the relationship between non-destructive tests and destructive tests. They test approaches include rebound value of rock Smith hardness hammer, uniaxial compressive test, point load test, and the ultrasonic test. Comparison between literature and this study, verify the result tests obtained in this study which are meaningful and useful for engineering application in Taiwan.
