摘　　要：结合某会展工程的深基坑施工,对深厚淤泥地质条件下锚杆进行现场试验分析,确定在该场区各类地层中进行锚杆成孔、注浆、钢绞线及承压板安放等操作的可行性,验证设计估算的锚杆承载力能否达到设计要求,并得出地层的极限锚固力,便于设计优化调整锚杆参数,得出不同锚杆的适用条件,并针对淤泥地质下压应力锚杆施工提出了相应的措施要求,对后续工程具有一定的借鉴意义。Combined with the deep foundation pit construction of an exhibition project,the field test and analysis of the anchor bolt under the geological conditions of deep silt are carried out to determine the feasibility of anchor bolt drilling,grouting,steel strand and pressure bearing plate placement in various strata in the site area,to verify whether the anchor bolt bearing capacity estimated in the design can meet the design requirements,and to obtain the ultimate anchoring capacity of the stratum,It is convenient to design,optimize and adjust the bolt parameters,obtain the applicable conditions of different bolts,and put forward the corresponding measures and requirements for the construction of compressive stress anchor bolt under silt geology,which has a certain reference significance for subsequent projects.
