Device and method for gathering data to model the lateral load response characterization of a pile

摘要

Embodiments relate to an apparatus and method for performing a split-lateral load test. Embodiments use a double hydraulic jack to apply two lateral loads, having equal magnitudes and opposite directions, to the soil layer of an excavation for a deep foundation element. Data such as the magnitude of the lateral load and magnitude of the displacement of the loading mechanism upon application of the lateral load can be measured and/or recorded. Embodiments can yield soil modulus (E_s) information in a form analogous to a p-y curve, which can be used to design a pile structure and pile placement, and model a pile response to lateral loading using computer software. Embodiments do not require the casting of concrete, and allow the split lateral loading mechanism to be sequentially positioned, and apply lateral loads, at multiple depths in an excavation. Embodiments simultaneously apply bi-directional lateral loads at multiple depths in an excavation.
