一、概述近代在国际上曾采用在室内测量膨胀土的膨胀势的方法,可分两类:第一类包括在试验过程中使土样浸水饱和,而试验结束时土的吸力为零或接近于零。这类试验的主要优点是仪器设备和试验方法比较简单。第二类是在试验过程中可将土的吸力加以控制,所需仪器设备和试验步骤较复杂,且取决于试验时所要施加吸力的变化范围(如西班牙V·Escario设计的
I. Overview of the methods used in modern times to measure the expansive potential of expansive soils in the modern world can be divided into two categories: The first type involves immersing the soil sample in water saturation during the test, and the suction force of the soil is zero or close at the end of the test. At zero. The main advantage of this type of test is that the equipment and test methods are relatively simple. The second type is that the suction of soil can be controlled during the test. The required equipment and test procedures are more complicated and depend on the range of suction force to be applied during the test (as designed by Spanish V. Escario
