岩體的變模數與岩石材料及弱面分佈情況有關，亦受地下水及現也應力影響；若能考慮岩體破碎度，建立岩材與岩體變形之間的關係，則可以最符合經濟的條件下求取岩體工程的變形模數參數。本文蒐集各工程案件之試驗資料，如場孔內變形試驗(EMT)與室內試驗彈性試驗(SO)及靜彈性試驗(ES)之參數，並依其地點、地層及岩性整理分類其參數值，以建立各地區岩體變形模數的基本資料，以及各試驗參數間之關係性，期對工程實務有所助益。The deformation modulus of rock mass is not only dominated by the rock material properties and the discontinuity conditions, but the groundwater and the in-situ stresses also have an influence on it. If the relationship of deformation between rock material and rock mass is established in terms of the rock fracture degree, the parameter for the deformation modulus of rock mass can be obtained. In this study, the experiment data inlcuidng the field elasotmeter test (EMT) and those gained from the laboratory ultrasonic test (SO) and static elasticity test (ES) for each project is collected. And then the corresponding parameters are classified and tabulated in accordance with the sample locations, the formations, and the rock types to establish the database of the deformation modulus of the rock mass in various regions. Hopefully, this will be helpful to the further research involving with the deformability of rock mass
