Abstract:
In order to investigate the elfeet of the deformation charaeteristies of partly-filled fracture on engi.neering stability, based on the experiment method of normal compression and lateral restraint, dynamie de.formation modulus of partly-filled fracture is researched. lt suggested that, the structure of filling medium be.gan to change owing to the elfeet of stress. The filling medium was smashed with the inerease of the stress. Atthe same time , the fracture spaee was filled with granules of medium till the spaee was full filled and the medi.um beeame dense. "The result is that deformation modulus had dynamie characteristies. The experimental re.sults showed that the deformation modulus of flled fracture inereases linearly with the inerease of stress, at thesame time , it has a high degree of reprodueibility. When the filled width is same, the deformation modulus olfilled fracture deereases with the deerease of the eonfiguration ratio of cement-sand. While the conliguration ra.tio of cement-sand is the same, the deformation modulus of filled fraclure inereases with the inerease of thefilled width.
