The research goal is to formulate and solve the problem of distributing the external load between piles with widening and a low grillage as part of a strip foundation in a flat setting and comparing the results obtained with experimental data. The design model of Flaman (the plane problem) and Boussinesq (the spatial problem) about the force applied on the surface and Melan's solution about the force applied inside the soil half-space are taken as the initial design models. An analytical calculation method was proposed, as a result of solving the problem. This method, with sufficient accuracy for practical purposes, allows to define the bearing capacity of the foundation on piles with widening and to estimate the distribution of the load between the piles and the grillage as part of the strip foundation. The proposed approach to solving the problem of load distribution between the grillage and piles with widening is important for design of strip foundations.
