Abstract:On-site quick identification of the degree of expansion of expansive soil is of great significance to practical engineering. A set of expansive soil identification device was developed based on Particle Image Velocimetry (PIV) technique, which can provide a constant temperature environment and stable image acquisition conditions under outdoor environment. This device was used to carry out laboratory tests on remolded expansive soils, and to establish a method of quick identification of the degree of expansion … Show more
