Abstract in Portuguese
Avalia-se o colapso de um solo residual, de comportamento laterítico, para líquidos inundantes de diferentes composições químicas, em profundidades de 1 até 4 metros, empregando-se provas de carga diretas e ensaios de adensamento. Explica-se o fenômeno do colapso, para cada líquido inundante, utilizando-se parâmetros obtidos em ensaios de caracterização, difração de raios X, microscopia eletrônica de varredura e ensaios químicos. A pesquisa é desenvolvida no Campo Experimental da UNESP de Bauru (SP), cujo solo local é uma areia fina argilosa, residual de arenito, enquadrada como Latossolo vermelho escuro a amarelo.

Abstract in English
The collapse of a lateritic residual soil is evaluated, using liquid of different chemical compositions, in depths from 1 to 4 meters, and using plate load and oedometer tests. This work explains the phenomenon of the collapse, for each liquid, employing parameters obtained in characterization tests, X-ray diffraction, scanning electron microscope and chemical tests. The research is developed in the Experimental Field of the Civil Engineering Department of the São Paulo State University (UNESP), at Bauru (SP), where the local soil is residual derived from sandstone, and according to grain size classification it is a clayey fine sand. In the pedological classification it is a dark red to yellow Latosol.
