在细观岩石力学试验中，研究试件在潮湿或化学腐蚀条件下裂纹的扩展规律非常重要。在这类试验中，常用的浸蚀装置是利用简单的塑料片粘贴于试件的表面，如Manabu UTAGA WA，Masahiro SET()，KunihisaKATSUYAMA and Kikuo MATSUI，Evaluation of Fracturre Tough-ness of Rocks in Wet and Chemical Conditon，资源匕素材，Vol.114，P.856—861(1998)。这样的浸蚀装置的最大特点是简单，但是，由于它需要根据试件的尺寸进行特制，并安装于试件表面，因此，在进行试验之前必须做大量的重复性工作，而且这样的浸泡只是试件的局部，它无法完成对整个试件的浸泡。另外，由于塑料片透明性差，它完全遮住了试件表面上的裂纹，影响了对裂纹的观测，这对研究试件在浸泡条件下裂纹的扩展规律十分不利。In mesoscopic rock mechanics tests, it is very important to study the crack propagation law of specimens under wet or chemical corrosion conditions. In this type of test, the commonly used etching device is to use a simple plastic sheet pasted on the surface of the specimen, such as Manabu UTAGA WA, Masahiro SET(), KunihisaKATSUYAMA and Kikuo MATSUI, Evaluation of Fracturre Tough-ness of Rocks in Wet and Chemical Conditon, Resource Dagger Material, Vol.114, P.856-861 (1998). The biggest feature of such an etching device is its simplicity, but because it needs to be specially made according to the size of the test piece and installed on the surface of the test piece, a lot of repetitive work must be done before the test, and such immersion is only Part of the test piece, it cannot complete the immersion of the whole test piece. In addition, due to the poor transparency of the plastic sheet, it completely covers the cracks on the surface of the test piece, which affects the observation of the cracks, which is very unfavorable for the study of the crack propagation law of the test piece under immersion conditions.
本实用新型的目的是针对上述浸蚀装置中存在的问题，提出一种岩石破裂过程加载试验装置中的浸蚀观测盒，它可以实现细观岩石力学试验在对整个试件进行浸泡的同时边加载边观测，而且提供多窗口进行多方位观测。The purpose of this utility model is to solve the problems existing in the above-mentioned erosion device, and propose a kind of erosion observation box in the rock fracture process loading test device, which can realize the mesoscopic rock mechanics test while soaking the whole test piece.
