During period of preparing the construction of halls of the industrial park, according to the geotechnical investigation were found adverse properties of soil. Below the ground surface was situated 5.5 m soft clay layer, deeper clayey gravel. Due to the nearby located river, the groundwater level was found just below the ground surface. Strict requirements to fulfilling first of all the serviceability limit state have led to the preparing the load test in real geological conditions in scale 1:1. Expecting load on ...

Measuring the behavior of building components during load tests is mostly done by the methods of length difference measurement. The most often used instruments are various types of dilatometers and inductive sensors, some offer excellent precision about level of micrometers. But problems such contact measurement, measurement of only one quantity (length), limited number of sensors located on object, need of cabling, possibility of instrument damage, high price of instruments, influence of other physical quantity o...
