ABSTRACT: In 2018, the Caisse de Dépôt et Placement du Québec (CDPQ) awarded a $6.3 Billion Design-Build contract to the Joint Venture (JV) team NouvLR (led by SNC-Lavalin) for the design and construction of the Réseau Express Metropolitain (REM) in Montreal. Out of the 67 km network, over 25 km will be constructed on elevated structure founded on single drilled shafts socketed into rock. In order to optimize the response of the shaft to lateral loading condition, the JV team performed two fully-instrumented lateral load tests in critical areas along the alignment. This paper presents a comparison of the lateral load test results with the lateral shaft response as simulated by LPile software, using several p-y curve models traditionally used for cohesionless and cohesive soils as well as for rock. The p-y curve as obtained from the pressuremeter tests are also compared to the lateral load tests.
