Abstract: From the end of the last century to the beginning of this century, restricted by many factors, such as, the social and economic level, the design and construction level of excavation support, and construction conditions at that time, the stone masonry retaining walls constructed were generally mainly dry masonry with less mortar, many cavities, and poor integrity. Under the combined effect of various objective factors, unstable phenomena such as common cracking, bulging, mortar missing, and even sliding and collapse were often observed, and the wall rehabilitation is required. During the rehabilitation construction of old stone masonry retaining walls, one of the key aspects is to ensure safety during the construction. Through practice, it is introduced that in the construction process of reinforcing old stone masonry retaining walls by the anchoring method, measures such as optimizing the construction sequence, construction equipment, and construction technology were adopted to effectively control the safety during the construction process and ensure construction safety. Practice shows that the above measures are feasible.
