Abstract (369) HTML (198) PDF (318KB)(19)
Abstract:
According to outcrops, formation microscanner logging (FMI), paleomagnetism oriented cores and stress variation difference experiment, a close study has been made on the natural fractures of super-lower permeability reservoirs in the Yanchang Formation of the Ordos basin, and in combination with mic...
EXPERIMENTAL RESEARCH ON MECHANICAL PROPERTIES OF LIMESTONE AND SANDSTONE UNDER HIGH TEMPERATURE
QIN Ben-dong, HE Jun, CHEN Lun-jian
2009, 15(3): 253-261.
Abstract (279) HTML (138) PDF (478KB)(14)
Abstract:
The mechanical properties of limestone and sandstone under high temperature were investigated by the experiment device used to heat rock designed by ourselves and servo-control testing machine RMT-150C. The results show that the longitudinal wave velocity of two kinds of rocks gradually reduced with...
APPLICATION OF LATTICE BEAM AND ANCHOR PIPE GROUTING COMPOSITE STRUCTURE TO FRACTURED ROCK SLOPE REINFORCEMENT

2009, 15(3): 262-269.
Abstract (208) HTML (92) PDF (243KB)(5)
Abstract:
The lattice beam and anchor pipe grouting composite structure is an effective engineering measure in landslide control. This paper deals with the mechanism of lattice beam and anchor pipe grouting, the principle and procedure of calculation by simplifying the lattice beam as Winkler elastic foundati...
