超前深孔预注浆在北京地铁中的应用研究

摘要

就超前深孔预注浆工法在北京地铁的应用进行了分析总结，研究发现目前超前深孔预注浆缺乏统一的设计标准，对于注浆的范围、方式以及材料的选择标准不一，针对该现象，建议对该工法进行规范化和标准化的设计，并从注浆的使用条件、施工方式、加固范围和浆液材料分别给出了详细界定。%The paper analyzes and sums up the application of the deep-hole pregrouting in Beijing subway,finds out the deep-hole pregrouting is lack of unified design standard,undertakes the regular and standardized design for the construction method according to the grouting scopes,ap-proaches and various selection standards for the materials,and defines the application condition,construction approaches,consolidation scopes and slurry materials.
