STUDY OF THE LOWERING OF THE WATER TABLE; INFLUENCE ON THE ENVIRONMENT

项目名称：	STUDY OF THE LOWERING OF THE WATER TABLE; INFLUENCE ON THE ENVIRONMENT
摘要：	THE LOWERING OF THE WATER TABLE IS OFTEN NECESSARY DURING LARGE-SCALE UNDERGROUND OPERATIONS. THIS MODIFIES SOIL EQUILIBRIUM IN THE VICINITY OF THE PUMPING ZONE AND, BY RESULTING IN AN INCREASE IN STRESSES BETWEEN SOIL PARTICLES, LEADS TO SOIL SETTLEMENT AND SETTLEMENT OF ANY STRUCTURE ERECTED ON THE SOIL. THIS INVESTIGATION DEALS WITH THE DETERMINATION OF SOIL CHARACTERISTICS, OF THE TYPE OF FIELD OF STRESSES TO WHICH THE SOIL IS SUBJECTED, AND PUMPING CHARACTERISTICS. A THOROUGH STUDY WAS MADE OF THE METHODS OF CALCULATING THE LOWERING OF THE WATER TABLE AND RESULTING CONSEQUENCES. A VERY RAPID METHOD OF DETERMINING THE HYDROLOGICAL CHARACTERISTICS OF WATER TABLES WAS DEVELOPED: STORAGE AND TRANSMISSIVITY COEFFICIENTS. THIS METHOD IS BEING TESTED ON VARIOUS SITES AND COMPARED WITH TRADITIONAL TECHNIQUES.
