　　巖石膨脹壓力試驗儀試驗步驟：

　　■將試件放人內壁涂有凡士林的金屬套環內，在試件上下分別放置薄型濾紙和金屬透水板。

　　■安裝加壓系統及量測試件變形的測表。

　　■應使儀器各部位和試件在同一軸線上，不得出現偏心荷載。

　　■對試件施加產生O.O1MPa壓力的荷載，測讀試件變形測表讀數，每隔l0min讀數1次，直至3次讀數不變。

　　■加的荷載，應保持試件高度在整個試驗過程始終不變。

　　■開始時每隔10min讀數1次，連續3次讀數差小于0.001mm時，改為每1h讀數1次

　　■浸水后總試驗時間不得少于48h.

　　■試驗過程中，應保持水位不變。水溫變化不得大于2℃

　　■試驗結束后，應描述試件表面的泥化和軟化現象。

　　Rock expansion pressure tester test steps:

　　■Place the test piece on the inner wall of the metal collar of Vaseline,ａnd place thin filter paper and metal permeable plate on top of the test piece.

　　■Installation of the pressure system and the measurement of the deformation of the test piece.

　　■The parts of the instrument and the test piece should be on the same axis,ａnd no eccentric load should occur.

　　■Apply a load of O.O1MPa pressure to the test piece,read the deformation table reading of the test piece,ａnd read it every l0min until the reading is unchanged.

　　■For the applied load,the height of the test piece should be kept constant throughout the test.

　　■Read every 10 minutes at the beginning,ａnd change the readings every 1h to 1 time for 3 consecutive readings.

　　■The total test time after water immersion shall not be less than 48h.

　　■The water level should be kept constant during the test.Water temperature change must not exceed 2°C

　　■After the test,the muddy and softened surface of the test piece should be described.
