Experimental Study On Bearing Capacity Of Structure Of Waste-tire Foundation

In recent years,the domestic and foreign scholars have studied the application of the waste rubber tire in civil engineering,and the application of the waste rubber tire in civil engineering will effectively relieve the environmental pressure.The constructed foundation of the waste rubber tire has the advantages of simple structure,reliable bearing,environmental protection and waste,low cost and the like,and can be realized without complicated design calculation and construction technology,and also can greatly improve the safety factor of the building structure of the villages and towns.The bearing capacity of the soil body under the side limit condition is higher than the bearing capacity of the no-side limit condition,the rubber tire generates a hoop effect on the soil body under the action of the load,the soil body can be effectively prevented from rapidly expanding outwards,the soil body in the rubber tire at the moment will have a lateral limit,so that the soil mass under the action of the rubber tire hoop is higher than the bearing capacity of the soil body under the action of the rubber tire hoop,and the structural form of the space also influences the hoop effect of the rubber tire,the rectangular column,the hexagonal column,the clip and the geotextile column are stacked in different spatial construction forms,The following results are obtained by using the same loading method and loading system under the same loading mode and loading system for four working conditions.The unique bearing mechanism of the constructed foundation of the waste rubber tire with respect to the natural ground is to construct the foundation in the vertical load,and the rubber tire will produce the hoop effect on the dispersion.With the increasing of the vertical load,the effect of the structure of the waste rubber tire on the hoop of the foundation soil becomes more and more obvious,and the form of the space structure is an important factor that influences the hoop effect of the tire structure foundation.In the five different working conditions,the bearing capacity is the largest,and the second is the condition of the column clamp and the layered working condition,and the last hexagonal column condition is larger than that of the column working condition.
