Abstract: Proof pile load tests are an important means to cope with uncertainties in the design and construction of pile foundations. In this paper, a systematic method to incorporate the results of proof load tests not conducted ...

Abstract: Failure of colluvial soil deposits induced by rainfall is a common geohazard in the natural terrain. Many colluvial soils are widely and gap graded with a minimal sand fraction. In order to study the pore water pressures ...

Abstract: Barriers are commonly used to intercept landslide flows or debris flows. The presence of a barrier changes the flow condition and leads to a buildup of earth pressure in a zone behind the barrier. Investigating this buildup ...

Abstract: An extreme rainstorm can cause thousands of landslides and kill hundreds of people. In the changing climate, fatal rainstorms become more frequent and intense. The current landslide emergency management evaluates hazard ...

Abstract: A method was presented to evaluate the reliability of axially loaded pile groups designed using the traditional concept of group efficiency along the lines of load and resistance factor design. Group effects and system ...

Abstract: An apparatus was developed to load large pile groups (3 × 3 to 7 × 3) founded in sand in the centrifuge laterally. The device consists of a hydraulic jack apparatus to install the piles, strain gauge instrumentation, and ...

Abstract: The coupled bridge foundation-superstructure finite-element code FLPIER was employed to predict the lateral response of the single piles and 3 × 3 to 7 × 3 pile groups founded in both loose and medium dense sands. The

Abstract: Empirical correlations with in situ or laboratory test results are routinely used in geotechnical designs and the uncertainty of prediction from these correlations can be substantial at times. This paper formalizes a ...

Abstract: This paper presents results of full-scale lateral load tests of one single pile and three pile groups in Hong Kong. The test piles, which are embedded in superficial deposits and decomposed rocks, are 1.5 m in diameter and ...
