锚定搅拌桩在基坑支护的应用

将土层锚杆直接锚定在强度相对较低的“薄型”搅拌桩墙上，锚杆用槽钢作为受压铁件与搅拌桩相接触。该支护工艺打丰了以往搅拌桩只设计成重力式厚挡墙及作为与灌注桩配合作挡水帷幕的传统做法，节省了许多工作量，做到了安全度高、造价低、噪音小、无污染、施工占有场地窄，可适用于闹市区或有近邻建筑的基坑支护施工。

Research on Stability Calculation Methods for Grillage Supporting Structure with Pre-stressed Anchor

Aiming at prestressed anchor cable frame in the presence of reinforcement landslide problem, through the selection of test points, the paper study and tested soil pressure, frame internal force and prestress losses under prestressed anchor cable frame beam, reveal the law of internal force distribution, and provides a theory basis for the rational design of prestressed anchor cable in landslide.
