Additional Lateral Soil Pressure on Soil due to The Vehicle at a Constant Speed

Abstract

On roads that cross the slope is often required evaluation of the need for retaining slope construction (road). In the design of the construction, one of the main factors that must be known is the amount of horizontal ground pressure that occurs. The amount of ground pressure consists of the ground pressure it self and the pressure due to other loads such as vehicles passing on it. The horizontal pressure due to constant and stationary loads is different from the horizontal pressure due to a running vehicle. This study was conducted to determine how the additional influence of horizontal pressure that occurs due to the vehicle through on it. A model (vehicle) is simulated to move at a constant speed along a sensor-Fed trajectory at a predetermined position. Instrumentation results show that the additional pressure that occurs in the form of pressure bubbles is similar to the pressure due to stationary and constant vertical loads. Test results for low-speed loads below 10 km/hrs showed the greatest horizontal pressure that occurs at a depth of 0.5 m and a distance of 0.5 m from the instrumentation. A comparison using the Boussinesq equation using the same load, shows that the maximum horizontal pressure that occurs is still relatively smaller than the additional lateral pressure due to static load.
