摘要
國內掩埋固化體大型試體之直接剪力試驗及單軸壓縮試驗求取力學參數之研究較付之厥如,其因除了掩埋固化體成份複雜、形狀差異極大、長期掩埋後物理及化學變化的影響外,更侷限於試驗設備之限制以及試驗進行缺乏自動化等缺失,所獲得之力學參數通常變異性也較大,試驗結果的可靠性也較不佳。
本文旨在研發研發自動控制及擷取系統,以利用電腦軟體來控制試驗進行與其數據擷取等,俾以改善試驗之缺失,並以大型掩埋固化體進行室內直接剪力與單軸壓縮試驗,用以驗證試驗系統及試驗程序。研究結果顯示使用傳統式加載正向應力,並配合正應力組合方法可得到較合理的剪力強度參數,至於多階段試驗方式以剪斷達每階段尖峰強度後再解載與加載的方法較易控制,而且所獲得結果也較接近傳統試驗成果。

關鍵詞:掩埋固化體、大型直剪試驗、多階段試驗。
Researches in reference papers in taiwan, large-scale specimen made of solidified waste the direct shear test and uniaxial compression test to strike a few mechanical parameters of the research field is scarce, solidified waste may be due to complex composition and shape differences or physical and chemical property changes in the long term buried history. Most part of it is more confined to the limitations of the test equipment and test scale and lack of automatic measurement system to grab the precise testing data which result in poor mechanics parameters obtained with greater variability in test data.
This article aims to develop automatic control and acquisition system, making best use of computer software to control the test with its data capture, help improving the deficiencies of the test, and the use of large solidified waste the indoor direct shear and uniaxial compression tests to verify the test system and test procedures. The research results show that using traditional ways loading normal stress, as well as with the normal stress combination obtained a more reasonable shear strength parameters as for the multi-stage test methods is the shear force, reaches the peak strength of each stage after to continue decompression and pressurized the way easier to control, Moreover the get results closer to the traditional way of test results.

Key Words:solidified waste ,large-scale direct shear test ,multi-stage tests.
