This article takes high side slope control project of two noth high cutting slopes between K35-K36 on the Jitai expressway as example and introduces the engineering practice of prestressed anchorage cable hanging net sprayed concrete supporting and retainting structure on controlling the dangerous rock and landslid.

Polypropylene fiber concrete has many unique engineering properties than normal concrete for tunnel lining in water conservancy engineering with high techno-economics effect and easy construction compared with hang net shotcrete.

In view of complex peripheral environment in the site of foundation pit of Science and Teaching Building of Wu- han First Hospital,information construction and combined supporting method were adopted with pile anchor retaining,soil nailing wall with mesh shot-concrete and concrete anchor.

Based on the basic thought of FEM,the model is set up before supporting the slope and after the combined support of the wire netting sprayed concrete and the presstressed anchorage cable.
