【 摘 要 】

Environment geotechnical engineer issue is an important question which involves geotechnical structure safety and sustainable development of ecology. Aiming to Yunnan latente's shear issue under condition of dry-wet cycle, the thesis took Yunnan latente's shear strength under function of dry-wet cycle as research content, and the result showed that along with increasing of dry-wet cycle, cohesion of laterite would reduce gradually, among them, amplitude of attenuation after the first dry-wet cycle is smaller, and it became bigger after the second and the third dry-wet cycle, cohesion is reducing gradually along with increasing of dry-wet cycle. Relation of internal friction angle and dry-wet cycle' times are tending to be gentle, among them, amplitude of attenuation is the biggest after the first dry-wet cycle, and internal friction angle has smaller attenuation amplitude after the second and the third dry-wet cycle. Peak strength with different load after dry-wet cycle have attenuation with different amplitude, there is bigger strength attenuation amplitude from the zero to the first dry-wet cycle, and it reduced later in proper order and arrived stable status after the third dry-wet cycle. Research of thesis has important meaning for guaranteeing safety of fundamental facilities engineer and provided reference and basis of engineer construction in Yunnan.
