摘要
灌浆工艺是影响土层预应力锚杆承载力的一个重要因素。结合实际工程,通过锚杆现场试验,就常压灌浆和二次高压灌浆两种灌浆工艺对富水土层中预应力锚杆承载力的影响进行了对比分析,认识到在富水土层中二次高压灌浆工艺能有效提高土层预应力锚杆承载力。
The grouting technique is an important effect that affects the bearing capacity of pre-stressed soil anchor. Based on the field test of the soil anchor, the effects on the bearing capacity of the pre-stressed soil anchor are compared and analyzed in terms of normal pressure grouting and secondary high pressure grouting, and it is recognized that the secondary high pressure grouting technique can effectively roise the bearing capacity of the pre-stressed soil anchor in the soil full of water.
