WPŁYW UPROSZCZEŃ MODELU NUMERYCZNEGO NA SYMULACJĘ ODWODNIENIA BUDOWLANEGO

Abstract

INFLUENCE OF ASSUMPTIONS IN NUMERICAL MODELLING ON THE SIMULATION OF BUILDING DEWATERINGMany building constructions require a building dewatering. Generally drilled wells are used for dewatering in excavation sites localized near the sea shore. According to the Polish Water Law 2001 (D.U. 2005 no. 239, 2019) elaboration of concrete project of dewatering is required. In actual calculation the governing equations are converted into applicable partial differential equations using a finite-difference approach. The credibility of calculations based on the assumed hydrogeological and numerical simplifications. In this paper the impact of grid dimension on groundwater table was studied.
