Abstract:

An indoor model test result of distribution regulation of strata resistance beside piles in the system of anchor anti-slide pile is introduced. In three test groups, two groups load on back of slope, the third one directly loads on the pile by jack. There are earth-pressure boxes on each pile to test the strata resistance. The distributing graphs of loading on the piles in the system is obtained from the tests. From the graphs, it is concluded that the strata resistance is focused on back of the piles. That is different from the anti-slide pile, in which the force is focused in front of the pile. Three distribution patterns of strata resistance beside piles in the system of anchor anti-slide pile and approximate scope for partial passive resistance values in front of the piles embedded the slide surface are given.

Key words: anchor anti-slide pile, test study, strata resistance of pile side, distribution pattern
