HYDRAULICS FOR LOWERING THE GROUND WATER TABLE USING VACUUM WELLS

AFTER SHOWING THE RELATIONS AND THE DIFFERENCES BETWEEN GRAVITATIONAL AND VACUUM HYDRAULICS, THE POTENTIAL DISTRIBUTION IN THE SEEPAGE FIELD DEVELOPING AROUND THE LINE OF VACUUM WELLS, IN THE CASE OF MORE IMPORTANT SUCTION, IS DISCUSSED IN DETAIL. THE RESULTS OF INVESTIGATIONS OF THE PARTICULARITIES OF THE MOVEMENT OF THE AIR IN GRANULAR SOIL PROVIDE THE THEORETICAL BASES FOR THE NUMERICAL CALCULATION OF THE AIR SEEPING INTO THE WELLS. THE DETERMINATION OF THE FLOW OF AIR AND WATER IN CASE OF A ROW OF WELLS ALONG ONE OR BOTH SIDES OF THE WORKING DITCH PROVIDES THE DESIGNER WITH NUMEROUS POINTS OF VIEW (E.G. OPTIMUM DISTANCE BETWEEN WELLS, POSSIBILITY OF EXCAVATING THE WORK DITCH). THE RESULTS REFERRING TO DRAINAGE PHENOMENA IN INHOMOGENEOUS SOILS ARE ILLUSTRATED BY THE INFAVORABLE CASES OF DRAINAGE. /RRL/A/
