The ultimate bearing capacity of footings resting on subsoils consisting of two layers has been investigated for the cases of a dense or stiff layer overlying a weak deposit, and a loose or soft layer overlying a firm deposit. The analyses of different modes of soil failure are compared with the results of model tests on circular and strip footings on layered sand and clay soils.

The aim of this article is to determine clay soils and clay soils mixtures deformations during drying. Experiments consisted from: a) clay and clay mixtures bridges (height ~ 0,30 m, span ~ 1,00 m); b) tiles of clay and clay, sand and straw (height, length, wide); c) cylinders of clay; clay and straw; clay, straw and sand (diameter; height). According to the findings recommendations for clay and clay mixtures drying technology application were presented. During the experiment clay bridge bearing capacity and failure mode were determined. For investigations Vilnius Gediminas Technical University Civil Engineering Scientific Research Center infrastructure was used. Tyrimo tikslas – nustatyti molinio grunto mišinių džiūvant atsirandančias deformacijas. Eksperimentams buvo naudojama: a) moliniai ir molio mišinių tiltai (aukštis ~0,30 m, tarpatramis ~1,00 m, plotis 0,07–0,1 m); b) plytelės iš molio; molio, smėlio ir šiaudų (l; b; h); c) cilindrai iš molio; molio ir šiaudų; molio, šiaudų, smėlio (d; h). Pagal gautus bandymo rezultatus pateiktos rekomendacijos molinių gruntų mišinių džiovinimo technologijai taikyti. Nustatyta molinių tiltų laikomoji galia ir suirimo pobūdis. Atliekant tyrimus buvo pasinaudota Vilniaus Gedimino technikos universiteto Civilinės inžinerijos mokslo centro MTEP infrastruktūra.

Clay is a type of soil with a high level of water content. These properties make clay soils have a low low bearing capacity which can have an impact on the buildings above them, such as cracked walls, raised foundations, bumpy roads and so on. The soil in Kedungsigit Village, Karangan District, Trenggalek Regency is clay and needs to be repaired to build a strong building. This study aims to modify the value of the bearing capacity of clay.  Modifications were made by adding Zeolite with a percentage of 0%, 5%, 10%, 15%, and 20%.  Zeolite is used because it contains mineral kristal alumina silikat which have the ability to bind grains between aggregates.  Observations were made on  the characteristics of clay including testing of volume weight, shear strength, and bearing capacity  using the Terzaghi method. The results showed the optimum value for the addition of 15. In testing the bearing capacity of the soil using the tread foundation, the value of 32,470 t/m2 was obtained for the addition of 15% zeolite and 21,376 t/m2 for the original soil.   From these results it is known that the use of zeolite can increase the value of the bearing capacity of the soil. So that these modifications can be used as an effort to improve soil in Kedungsigit village.
