FAILURE PATTERNS OF THE GROUND SURROUNDING RIGID PILES IN SAND SUBJECTED TO LATERAL SOIL MOVEMENTS
Laboratory model tests in sand were conducted to investigate three-dimensional failure patterns of the ground surrounding a single rigid pile and piles in a row subjected to lateral soil movements (passive piles). An apparatus for the tests was designed and manufactured in which an automatic loading system under displacement control was incorporated. To help observe and identify the slip surfaces, thin layers (5mm) of colored and uncolored Toyoura sand were alternately laid up to prepare a uniform model ground with an almost same soil density for all the tests. By cutting the model ground after the tests, the geometry of the failure surfaces developed in sand was observed and measured both in longitudinal/cross sections and in horizontal sections using manual measurement techniques and a simple image processing analysis. Experimental results are reported to show three-dimensional failure patterns of the sand ground around single piles and piles in a row subjected to lateral soil movements.
