動力三軸試驗主要用來評估土壤動態性質與動態強度,發展至今已成為目前大地工程動態試驗中應用最為廣泛的試驗之一,以往的動力三軸試驗為非自動化試驗,試驗較為冗長且複雜,且人為因素為主要誤差來源,故電腦輔助自動化試驗之研究是勢在必行的。
近幾十年,電腦科技呈跳躍式的進步與廣泛的發展,使得以往所完成的電腦輔助試驗程式在沒有更新之下,已無法相容於目前的作業系統。
本研究採取了新一代的程式語言Visual Basic 2005進行動力三軸試驗程式視窗化(CTTP)之研究,利用圖形使用者介面(GUI)與物件導向(OOP)等方式來建構本程式,使動力三軸試驗程式不僅相容於目前一般的作業系統,更因為視窗化介面的使操作更為人性化。整體設計中亦加入資料擷取卡,使量測精準度提升至98%以上。程式的流程參照ASTM D 3999 - 91(2003)與D 5311 - 92(2004)所建議之動力三軸最新規範,使試驗結果更具代表性。本文亦對動力三軸基礎理論、試驗儀器、試驗流程、結果分析以及動力三軸試驗程式各主要表單之設計原理進行介紹,方便使用者更熟悉動力三軸自動化試驗程式之設計。
The purpose of cyclic triaxial test is used to evaluate the cyclic properties and strength of soils. The cyclic triaxial test has become one of the most useful geotechnical tests since it was developed in 1960s. In the beginning, the cyclic triaxial test is a manually test, and the test time consuming and complicated. The errors are mainly caused by tester. Therefore, developing the automated cyclic triaxial test is necessary.
It is because of the computer technology blooming for the last several decades that the past version of automated cyclic triaxial test is not compatible with the new operating system.
In this study, the programming language of Visual Basic 2005 is used to develop the new cyclic triaxial test program system. Based on the graphical user interface (GUI) and object-oriented programming (OOP) techniques, the developed program is compatible with the new operating system and friendly with user. There are discussed in this study. In addition, the theory and test procedure of the cyclic triaxial test programming (CTTP), and the algorithms of the CTTP program are presented in this thesis.
The new data acquisition instrument is used to enhance the accuracy in the test process up to 98%. The procedure of automated program is referred to ASTM D 3999 - 91 (2003) and D 5311 - 92 (2004). This thesis contains the fundamental theory of cyclic triaxial test, equipment, test procedure, result analysis, and the algorithms of the design of program.
