PURPOSE: A method for evaluating safety on a retaining wall work field is provided to perform an accurate evaluation through the correction of a management standard value in which a safety coefficient and a damage weight index are applied. CONSTITUTION: The horizontal displacement data of a retaining wall is collected in a construction field. The horizontal displacement management standard value of the retaining wall is calculated from the horizontal displacement data. The axial force data of a support and the horizontal displacement data of the retaining wall are obtained. A level of collapse risk is calculated from the tendency according to correlation of the horizontal displacement and axial displacement. The index of a collapse weight is calculated from the calculated level of the collapse risk. Through comparing the horizontal displacement data and modified horizontal displacement management value, a collapse risk is calculated. |
