Abstract Research purposes: For the deep soft soil or soft rock cutting，the traditional engineering measures of the toe retaining wall or the slope end supporting with anchor pile is often taken to reduce the slope height，remain the slope stability and avoid the rock moving away and destroy mountain and vegetation massly． However，under the condition of the mechanized construction in large scale，there are the security risks when taking these measures． For building such kind of the slope of passenger dedicated line，the toe low retaining wall and the uper steep slope are used in order to well control the slope height，cut the construction risk，be convenient for construction and ensure the construction security and the long － term stability of the slope as well as to meet the requirements of greening the environment，saving the mason and reducing the investment． So it is necessary to reinforce the prestressed anchored frame beam in grade．

Research conclusions: For the soft soil or soft rock cutting，the light structure of combination of the dense spacing prestressed anchored frame beam to the steep slope with the toe remaining wall is used，and the appropriate vegetation measure is taken in the anchored frame beam，with the features of mature technology，advanced process，rationality and reliability． So，it can be widely applicated．

Key words： slope reinforcement anchor prestress frame beam rebar
