坡积土 meaning in Chinese

clinosol
colluvial soil
slope wash soil

Another hidden danger is the weakening of the impervious ability of the dam resulting from the closeness of the height of line seepage of the reservoir water level to the contact plane between the residual solum , talus solum and basement rocks
水库水位浸润线标高和残坡积土与基岩接触界面标高较接近，而使此高程的防渗能力更加薄弱，这也是此坝体的隐患之一。
The geologic condition of side slope is complex . it is composed of soil and intense weathering rock on the surface and slightly weathering rock under the surface . further more , it has many faults , fissuring and weak intercalations
其水电站尾水渠高边坡所处区域地质条件复杂，边坡表面由几米至十几米厚的坡积土和强风化破碎岩石组成，下部是弱风化和微风化岩石组成，且断层、节理和软弱夹层分布广泛。
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
建议采取截渗墙结合帷幕灌浆作垂直防渗体为主的防渗措施，同时充分利用坡积土和全风化带作为水平防渗铺盖以减少防渗处理工作量。
