CALCULATION MODEL AND TESTING ON A NEW SORT OF SPREAD FOUNDATION WITH CONCRETE SLAB

摘要：

The background reaction and reinforcement bar stress of a new sort of foundation named “Spread Foundation with Concrete Slab now are solely tested by two kinds of sensors called GYH-2 and GJL-2. At the same time, the foundation settlement is also tested by a kind of equipment called N3 in-situ monitoring. So the first-hand dynamic data have been griped. The allocation proportion of background reaction between spread foundation and concrete slab and reinforcement bar stress can be nailed down. The regularities of spatial distribution and virtual condition of the new foundation are also confirmed. The practical calculation model is nailed down based on the test data, and the calculation formula about allocation proportion of background reaction can be deduced too. As a result, concrete slab can take on about 30％ the upper load of structure. Reinforcement bar stress changes alternately, the biggest tensile stress occurs at span centre of slat under the poles, it displays about 22％ of reinforcement bar intensity less than allowable value.
