A Calculation Model of Grout Migration Height for Post-Grouting Technology
نویسندگان
چکیده
Post-grouting technology has been extensively used in geotechnical engineering to improve the bearing capacity of various piles, which overcomes technical limitations bored piles and recovers mechanical performance strata. A considerable amount earlier research conducted investigate behavior reinforcement mechanism grouted while very few studies focus on area post-grouting technique. The theoretical analysis is great significance, beneficial correlate grouting parameters with pile a target saving cost acquiring an optimized design. This paper grout migration height, then proposed new predictive model estimate ultimate height cement slurry, where rising process considered as flow Bingham fluid axial annular space. field test was verify applicability model, comparison results revealed that calculated slightly overestimated compared actual values, but it acceptable pressure loss induced permeation warranted be studied future.

Cement grouting is an operation often carried out to consolidate and seal the rock mass in dam sites and tunnels. The quality and efficiency of a grouting operation depends on various factors such as water take, grout properties and grouting pressure. One of the parameters which have the highest effect is pressure since the application of excessive pressure causes the hydraulic fracture phenome...
