风积土地区工程病害分类和防治系统化研究
Engineering Disease Classification and Control in Aeolian Soil Area
摘要
Abstract
As for the disease classification,influencing factors and controlling measurements for Aeolian Soil engineering in western Liaoning Province of China,methods of field investigation,indoor experiment and construc-tion requirements analysis are used.The disease classifications are obtained in terms of disease phenomenon and disease mechanism respectively,then analyzing the four-level influencing factors under the Engineering-Geosphere System and Analytic Hierarchy Process,and giving the controlling measurements,thus forming the systematical and simple frame for engineering disease identification and control.The results show:①Aeolian Soil is silty clay with coarse granule,good gradation,medium compressibility,low shear strength,easy liquefaction,apparent structure and non-obvious collapsibility;②Engineering disease in Aeolian Soil area often develops under the reason of com-pressible settlement,shearing damage,vibration-subsidence and liquefaction,collapsibility,frost-heave and thaw-settlement,weathering,current scour,etc.;③Based on the Engineering-Geosphere System,the main influencing factors for engineering disease in Aeolian Soil area are physicomechanical property of Aeolian Soil,human activity and natural environment;④It’s necessary to establish systematical frame of disease identification,adjusting and control,thus making the work normative,processive,standardizing and informatized.关键词
