粉喷桩处理河道滑坡的实例应用及探讨

在南方城市内河整治工程中，通常法满足大范围放坡，且内河边坡和河底土质均较差，河道开挖过程中容易产生滑坡，影响河道成型和周边建筑物安全。河道滑坡治理采用水泥粉喷桩复合地基能够有效地解决河道软基的低抗剪性，提高边坡稳定性。本文结合工程实例，介绍了利用水泥粉喷桩的抗剪强度，提高河道边坡抗滑稳定性的成功经验。

The Example Application and Exploration of the River Landslide Treat ment with Cement Powder-spray Pile

In the southern city, the river improvement works usually can not make large-scale slope. Meanwhile, because of the bad soil quality in the river scope and bottom, the land sliding often happens during excavation of river bank. So bad affection to the forming of river bank and the safety of surrounding building are taken place. In the process of river landslide treatment, using the cement powder-spray pile composite foundation can effectively solve the problem of low-shear soft river bank and also enhance the stability of slope. Based on an engineering project, some successful experence of increasing the anti-slide stability of river bank by means of the shear strength of cement powder spray pile was presented in this paper.
