Firstly , the main deformation and destruction forms of high loess slope and its deformation and destruction mode are brought forward . the forms are : collapse , slumping , slope wash , slope peeling , sliding mass deformation by collapsibility , and a very little seen form : mudflow 根據野外調查和前人的研究資料,概括總結出黃土高邊坡有如下幾種破壞形式:滑塌、崩塌、坡面沖刷、坡面剝落掉塊、坡體濕陷變形以及并不多見的泥流。

Because the road line is in mountainous region and heavy hilly area and its surface relief undulates greatly , more slope wash and dilurial layer distribution , there are more harm , for example , island shaped perennially frozen soil , drift ice and so on , which effect the stability of the road foundation 由于沿線地處山嶺重丘地區,地勢起伏較大,坡積物及洪積層分布較多。故島狀多年凍土、涎流冰等病害較多,影響路基的穩定。

It is suggested that the impervious wall combined with curtain grouting should be taken as the main vertical impervious body for seepage control , and that the full use of slope wash and fully weathered zone as horizontal impervious blanket should be taken to reduce work load for seepage control 建議采取截滲墻結合帷幕灌漿作垂直防滲體為主的防滲措施,同時充分利用坡積土和全風化帶作為水平防滲鋪蓋以減少防滲處理工作量。
