Hoe I. Ling, Auteur ; Huabei Liu, Auteur ; Victor N. Kaliakin ; Leshchinsky, Dov ; Landis, Eric N., Éditeur scientifique |An advanced generalized plasticity soil model and bounding surface geosynthetic model, in conjunction with a dynamic finite element procedure, are used to analyze the behavior of geosynthetic-reinforced soil retaining walls. The construction beh[...]

Hoe I. Ling, Auteur ; Min-Hao Wu, Auteur ; Leshchinsky, Dov, Auteur |This paper demonstrates the use of a centrifuge modeling technique in studying slope instability. The slope models were prepared from sand, and sand mixed with 15 and 30% fines by weight, compacted at optimum water content. The validity of the m[...]

Hoe I. Ling, Auteur ; Leshchinsky, Dov, Auteur ; Mohri, Yoshiyuki, Auteur |This paper reports on the seismic performance of three geosynthetic-reinforced segmental retaining wall systems backfilled with a silty sand mixture, using a shaking table excited by 1995 Kobe earthquake loadings. The preparation of the backfill[...]

Leshchinsky, Dov, Auteur ; Baris Imamoglu, Auteur ; Christopher L. Meehan, Auteur |An instrumented geogrid-reinforced wall constructed on a highly compressible foundation was deconstructed 16 months after its completion, providing a unique opportunity to exhume and examine the instrumented geogrids that were used to construct [...]

Hoe I. Ling, Auteur ; Yang, Songtao, Auteur ; Leshchinsky, Dov, Auteur |A finite-element procedure was used to simulate the dynamic behavior of four full-scale reinforced soil retaining walls subjected to earthquake loading. The experiments were conducted at a maximum horizontal acceleration of over 0.8 g, with two [...]

Leshchinsky, Dov, Auteur ; Farshid Vahedifard, Auteur |Reinforced masonry block retaining walls are comprised of a narrow column of stacked blocks at their exposed end. This column is placed on a nonstructural leveling pad to facilitate the placement of facing units. Theoretically, this column can g[...]

Leshchinsky, Dov, Auteur |Common design of MSE walls is based on a lateral earth pressure approach. A key aspect in design is the determination of the reactive force in each reinforcement layer so as to maintain the system in equilibrium. This force leads to the selectio[...]

Farshid Vahedifard, Auteur ; Leshchinsky, Dov, Auteur ; Christopher L. Meehan, Auteur |This paper presents an integrated analytical method for calculating the resultant unfactored geosynthetic force in reinforced earth structures under seismic loading conditions. The method utilizes a pseudostatic limit equilibrium approach for as[...]

Leshchinsky, Dov, Auteur ; Fan Zhu, Auteur ; Christopher L. Meehan, Auteur |Current reinforced earth structure designs arbitrarily distinguish between reinforced walls and slopes, that is, the batter of walls is 20° or less while in slopes it is larger than 20°. This has led to disjointed design methodologies where wall[...]

Leshchinsky, Dov, Auteur ; Fan Zhu, Auteur |Traditionally, resultant force of lateral earth pressure serves as the basis for design of nearly vertical walls. Conversely, slopes are designed to be internally stable using a factor of safety approach. However, with the availability of heavy [...]

Hoe I. Ling, Auteur ; Leshchinsky, Dov, Auteur ; Jui-Pin Wang, Auteur |This paper summarizes the seismic response of five large-scale retaining walls having a geocell facing. The walls were 2.8m high and the backfill and foundation soil were a fine sand compacted to 90% standard Proctor density (relative density of[...]
