Development and its Applicability of Portable Ground Bearing Capacity Device

摘要

Geotechnical investigations of site and bearing capacity analysis are very important procedures for construction of building. Plate loading test is conventional method usually used to measure a bearing capacity of ground directly. But this method is not used widely because it needs large measurement space, long time for measurement and rather costly for single house foundation survey. Therefore, development of easy and cheapest way of bearing capacity survey is keen interest of Japanese geotechnical engineers. In this context, the authors have developed a portable ground bearing capacity survey instruments that could solve aforesaid problems associated with plate loading test. The relationship curve between the loading pressure and penetration directly gives the ground bearing capacity value.
