YZP-1岩石自由膨胀率试验仪试验步骤:

★将试件放人自由膨胀率试验仪内,在试件上下分别放置透水板,顶部放置一块金属板。

★在试件上部和四侧对称的** 部位分别安装千分表。四侧千分表与试件接触处,宜放置一块薄铜片。

★读记千分表读数,每10min读记1次,直至3次读数不变。

★缓慢地向盛水容器内注人洁净水,直至淹没上部透水板。

★在第1小时内,每隔l0min测读变形1次,以后每隔1h测读变形1次,直至3次读数差不大于0.001mm为止。浸水后试验时间不得小于48h。

★试验过程中,应保持水位不变,水温变化不得大于2℃

★试验过程中及试验结束后,应详细描述试件的崩解、掉块、表面泥化或软化等现象。

YZP-1 rock free expansion rate tester test steps:

★ Put the test piece in the free expansion rate tester, place a water permeable plate above and below the test piece, and place a metal plate on the top.

★ Mount the dial indicator on the upper part of the test piece and the symmetrical parts on the four sides. A thin copper sheet should be placed where the dial indicator on four sides contacts the test piece.

★ Read and read the dial indicator, every 10 minutes, until 3 readings remain unchanged.

★ Slowly pour clean water into the water container until the upper permeable board is flooded.

★ In the first hour, measure the deformation once every 10min, and then measure the deformation once every 1h, until the difference between the three readings is not more than 0.001mm. The test time after immersion in water shall not be less than 48h.

★ During the test, the water level should be kept constant, and the water temperature change should not be greater than 2 ℃

★ During the test and after the test, the phenomena of disintegration, block dropping, muddying or softening of the test piece shall be described in detail.


YZP-1岩石自由膨胀率试验仪膨胀率计算:

按下列公式分别计算岩石自由膨胀率、侧向约束膨胀率、膨胀压力

VH=△H/H *100

VD=△D/D *100

VHP=△H1/H *100

PS=F/A

式中:

VH——岩石轴向自由膨胀率(%)

VD——岩石径向自由膨胀率(%)

VHP——岩石侧向约束膨胀率(%)

Ps——岩石膨胀压力(MPa)

△H——试件轴向变形值(mm)

H——试件高度mm

△D——试件径向平均变形值(mm)

D——试件直径或边长(mm)

△H1——有侧向约束试件的轴向变形值(mm)

F——轴向荷载(N)

A——试件截面积(mm2)


岩石轴向自由膨胀率、径向自由膨胀率、侧向约束膨胀率试验结果** 至0.1%,

岩石膨胀压力试验结果** 至0.001MPa.

YZP-1 Rock Free Expansion Rate Tester Expansion Rate Calculation:

Calculate the free expansion rate, lateral restraint expansion rate, and expansion pressure of the rock according to the following formulas

VH = △ H / H * 100

VD = △ D / D * 100

VHP = △ H1 / H * 100

PS = F / A

In the formula:

VH——Rail axial free expansion rate (%)

VD-radial free expansion rate of rock (%)

VHP-lateral restraint expansion rate of rock (%)

Ps-rock expansion pressure (MPa)

△ H——Axial deformation of test piece (mm)

H—— height of test piece mm

△ D——The average radial deformation of the test piece (mm)

D——Diameter or side length (mm)

△ H1——Axial deformation value of specimen with lateral restraint (mm)

F-axial load (N)

A——Sectional area of test piece (mm2)

Test results of axial free expansion rate, radial free expansion rate, and lateral restraint expansion rate of rock ** to 0.1%,

Rock expansion pressure test results ** to 0.001 MPa.
