对既有支护结构的加固是有效延长结构使用寿命的一种方式。本文以某边坡加固为例，采取在原结构前设置锚索桩板墙并与墙后填土及原结构共同作用的加固方式，提出综合性边坡支护加固设计流程，包括土体沉降与滑移成因评估、加固方案设计、施工顺序设计与信息化监测等。结合工程实际，在设计阶段充分考虑边坡的地质条件、荷载特点及周围环境。现场检测验证了该加固方法的有效性。

Strengthening existing support structures offers an approach to extend the service life. This paper presents a case study of slope reinforcement. A comprehensive slope reinforcement design process is proposed, involving the installation of anchor sheet-pile wall in front of the existing structure, synergizing with the backfill soil and the existing structure. This process encompasses stages such as evaluating causes of soil settlement and sliding, designing reinforcement scheme, planning construction sequences, and implementing informatized monitoring. By integrating practical engineering considerations, including the geological conditions of the slope, loading characteristics and environmental factors, an assessment is performed during the design phase. The effectiveness of the proposed reinforcement approach is validated through on-site engineering testing.
