TEST METHOD FOR DETERMINING LONG-TERM COMPRESSIVE CREEP OF GEOSYNTHETICS

摘要

An acceleration compression creep method of drainage geosynthetics is provided to reduce the error rate of measurement data by increase the temperature of a teat piece step by step. An acceleration compression creep method of drainage geosynthetics comprises followings. The tilt angle(A) of a test piece is fitted based on the tilt angle of an under construction slope. The test piece is temperature-ascended gradually. The compressive stress is given. The temperature of the test piece is increased by heating up a clamp griping the test piece. An angle adjusting clamp(30) grips the test piece. The angle adjusting clamp is pivotally installed. The test piece of the drainage geosynthetics can be compressed by the angle adjusting clamp according to the various tilt angles.
