岩石膨胀性试验注意事项探讨
摘要:从室内试验的角度来探讨几类工程勘察中岩石常用膨胀性试验（自由膨胀率、膨胀力、侧向约束膨胀率、耐崩解）的注意事项，从野外取样、标准样品制取、试验操作、方法选择等方面进行了论述，力求减小试验误差，提高膨胀岩的试验水平，保证试验结果的准确性，并使膨胀岩膨胀性指标的测定方法更臻完善。
Abstract:The important points of the expansion test (free expansion rate, expansion force, lateral restraint expansion rate, and collapse resistance) in several kinds of engineering investigations are discussed from the perspective of laboratory tests. The field sampling, standard sample preparation, test operation and method selection are discussed. Through the summarized methods, the test error could be reduced, the test level of expansive rock could be improved, the accuracy of test results could be guaranteed, and the method of measuring expansion index of expansive rock could be improved.
