后置锚杆在某工程基础抗浮中的应用

Application of Postpositioned Anchorage in Some Foundation Anti-floats

为解决大型地下室基础抗浮问题,采用了后置锚杆抗浮技术,根据现场的实际情况和地质条件,通过现场试验研究,对锚杆成孔、泥浆护壁、注浆和锚索安放等工艺进行调整和改进,确保锚杆极限承载力。

In order to solve the large-scale basement foundation anti-to float the question,used the postpositioned anchor rod anti-to float the technology,according to the scene actual situation and the geological condition,through the field test research,to crafts and so on anchor rod Cheng Kong,mud counterfort,note thick liquid and anchor cable imposition carried on the adjustment and the improvement.Guarantees the anchor rod limit supporting capacity.
