   要:三轴试验广泛应用在土力学试验中,用于测量土壤强度和变形等特性。试样在高围压、重载荷下的获得的排水量是衡量试样体变的一个重要指标,排水量的测量精度决定试验的成败。然而,针对直径1.0m、高2.0m的超大试样,试验过程中超大试样向外排水量将达到160L,甚至更高,并且流量不均匀,流速时快时慢,排出时间长。传统的排水量检测方法由主观、客观原因很难满足对其高精度连续测量。该文对常用的传统排水量测量方法的特点进行了分析与梳理,详细阐述了传统排水量测量方法对超大试样排水量测量所面临的难题,最后提出一种满足超大三轴试验中超大试样体变(排水量)特点的连续高精度测量装置设计方案,并对该方案进行了试验验证,试验结果表明,该装置测量精度较高,装置稳定性较好,能够实现对超大试样排水量连续高精度检测。

AbstractTri-axial test is one of the most common soil tests, which can be used to measure soil characteristics such as strength and deformation etc. Water drainage obtained from test samples compressed by high confined pressure and heavy load is a key measurement index of specimen deformation. The measurement precision on water drainage determines the success of the test. However, for a huge test sample of a diameter of 1.0 meters, 2.0 meters high, water drainage can reach 160L, Or even higher, with a nonuniform flow, a faster or slower flow rate as well as a long time drainage. The traditional measurement methods are difficult to meet the high-precision continuous measurement due to subjective and objective reasons. In this paper, firstly, there is a analysis about the characteristics of the traditional measurement methods for water drainage. Then, this article analyzes the problems which traditional measurement methods face to achieve high-precision continuous measurement for water drainage obtained from a huge test sample. Finally, this paper proposes a solution to achieve high-precision continuous measurement of large, very large water drainage. According to result from the experiment, This solution shows higher measuring accuracy, stronger stability and can achieve high-precision continuous measurement for water drainage obtained from a huge test sample.

Key wordslarge tri-axial test; huge water drainage; high precision; continuous measurement

   要:该文对ISO 6358-22013)等温容器放气法计算临界压力比b值的方法的可信性提出了质疑。利用等温放气法测量Cb值,有两点需要讨论,第一,测流动中的气体压力,应流动达稳定时才能正确测量。对等温放气法,测气罐内的瞬态压力随时间的变化曲线,测出的瞬态压力与该时刻的真实压力有多大误差?第二,该偏差对确定Cb值会带来多大的影响? Cb值的均方根误差分析表明,测量仪表的精度宜使用特级,不宜使用A级。特级测量精度计算b值的最佳的供气压力在0.20.5bar(g)之间,故对流通能力小的元件及有最低使用压力要求的元件,不宜使用本方法。对同一个被测阀,用各种方法测量其S值和b值,发现等温放气法测不出S值和b值,但用定压法和串接法,测出的S值和b值都非常接近。

AbstractIn this paper, ISO 6358-2 (2013) isothermal container discharge method to calculate the critical pressure ratio b value method is credibility questioned. Using the method of isothermal discharge measuring C, b values, there are two points that need to be discussed, first, the gas pressure in flow measurement, should be flow stability to correct measurement. For isothermal discharge method, measuring the transient pressure inside the tank along with the change of time curve, measure the transient pressure and the moment of truth has much error? Second, the deviation to determine the C, b values will bring much impact? To C and b values of root mean square error analysis shows that the precision measuring instruments should use premium, should not use A-level. Super precision measurement and calculation of optimal b value of supply pressure between 0.20.5bar (g), so the flow capacity of small components and there are elements of the minimum requirements for the use of pressure, should not use this method. The same valve to be tested, using various methods to measure the S value and b value, found that isothermal container discharge method couldn't measure the S value and b value, but with constant pressure method and the method of concatenated, measure the S value and b value is very close.

Key wordsisothermal container discharge method; international standard; flow-rate characteristics; sonic conductance;  critical pressure ratio; effective area; root mean square error analysis
