Scholars at home and abroad calculate the gravity function separately to perform the un-strip shallow footings bearing capacity. The geometry of failure mechanisms is three-dimensional. Cohesion force

overloading and gravity are coupled to calculate the bearing capacity with limit equilibrium theory. Several parameters influencing the calculation result of bearing capacity are discussed. The factors calculated are typically larger than earlier empirical proposals in the literatures. The comparison of results with existing solution is given to validate the method.
