Loess Joints Development Characteristics and Space Partition

Abstract:

The extensive development vertical joints is one of the major features in the loess region. The joint destroyed the loess slope integrity, reduces the slope stability. First of all, through the field investigation and analysis the loess joint development characteristics, joint with slope tendency towards a big angle oblique, joints control slope trend. Secondly, according to the different regional slope stress analysis, tableland soil area is mainly by collapsibility tension, soil in the slope zone mainly by horizontal thrust produced by unloading effect, the slope area joint development is divided into collapsibility joint development zone, tension joint development zone, compression joint development zone and the excavation unloading joint development zone.
