摘　　要：有关非饱和土吸力量测技术的资料已有不少 ,但要准确地测量大范围的土吸力目前仍很困难。比较和讨论各种非饱和土吸力量测手段各自的优越性和不足点以及在工程中各自的应用领域。最后 ,还提出了关于更有效的吸力量测仪器的一些设想。Different techniques are available nowadays for measuring the suction of unsaturated soils. It remains, however, difficult to measure the soil suction with high accuracy. An attempt is made to compare and discuss the respective advantages and shortcomings of each measuring technique and suggest the best choice in different engineering applications. Some ideas on a more efficient instrument for measuring soil suction are presented.
