A heavy and homogeneous inviscid liquid lies between two half-planes, namely the free surface (y =0) ((x ge0)) and a rigid sloping beach (y = - x), in its state of rest at time (t = 0) (see Figure 1).
Single-crawler tests on simulated lunar soil revealed that the crawler's slip ratio was lower than that of a rigid wheel at any slope angle, and that its power consumption was lower than that of a wheel on slopes of 10° or more.
In this paper, based on wheel attitude, dynamics of the wheel terrain interaction for a rigid wheel on deformable slope is investigated.
This research was initiated in order to investigate the capability of rigid strip one side micro-piles footings in stabilizing sand slopes.
In Figure 4, a rigid slice with unit width and unit thickness is chosen to evaluate the safety factor for a slope.
The specified experiment was for uniform medium dense sand with a 5 degree slope in a rigid container subject to a ramped, 1 Hz sine wave base motion.
Fang et al. (1997) conducted the experiments on a vertical rigid retaining wall with a sloping backfill.
If a rigid body is static on the slope, the maximum absolute inclination angle to avoid slippage is calculated as (theta = arctan (mu ) = 0.42) [rad].
That is to say, the safety factor of the slope can be determined by analysis of a rigid wedge or rigid slice of material of unit width and unit thickness.
In these cases, certain assumptions (that is, rigid block movement) are made to simplify the slope condition and facilitate practical calculations.
