Evaluation of the Effectiveness about Hydrostatic Pressure Relief Technology for Structures at Mountainous Terrains

Abstract

The subdivision and development of the mountain terrain is formed under the condition of geological, soil water conservation, foundation buoyancy and lateral seepage pressure caused by the groundwater. This issue is exacerbated by global warming and environmental change. The unpredictable nature of underground water fluctuation can have detrimental effects on the quality of underground infrastructure, and often reduces the functional viability of basement space in a building. The effects of groundwater on the structural stability must be carefully evaluated and analysed during the planning stage before construction. Proper mitigation measures must be developed to prevent any possible structural damage or basement leakage. Practical construction experiences and figures show that the use of drainage and anti-floating method "Hydrostatic Pressure Relief technology (HPR)" can effectively control the encountered groundwater problems for subdivision and development at mountainous terrains. It is also valid to impede basement sidewall leakage and capable of serving as an effective means of damp proofing. The relief of hydrostatic pressure through a water distribution system makes underground spaces more resilient and adaptable, thus reducing their vulnerability to future climate changes.
