注浆微型桩受弯能力试验研究与工程应用

Experimental and Engineering Application on Grouting Micro-pile with Flexural capacity

通过微型桩受力能力试验,得到了微型桩荷载与挠度的关系,以及微型桩的屈服荷载和对应的挠度、弯矩;同时,得到微型桩荷载与钢筋计应力的对应关系。结合宝鸡市安台村滑坡治理工程,通过微型桩极限荷载时的应力与现场实测数据对比,判断微型桩的受力状态。加固后的滑坡稳定性良好。

Through the test on micro-pile in force, the relation between the pile load and deflection, the yield load, and the corresponding deflection and bending moment were found out, at the same time, the correspondence relation between the micro-pile load and the stress of reinforcement meter was obtained. Combining with the landslide control project in Baoji city, the stress in ultimate loading of the micro-pile was compared with the field measured data to judging the stress state of the micro-pile. After reinforced, the stability of Antai Village Landslide is good.
