Thick bedrock thin topsoil 厚表土薄基岩
The following main results and conclusions have been achieved:(1) For the shallowly-buried thin bedrock with thick loess, if the surface sand is loose(without self loading capacity), the bedrock will not form self stable structure until it reaches certain thickness.
取得了以下主要成果与结论:（1）对于厚表土浅埋薄基岩,若表土为松散砂土（假设无自承能力）,基岩达到一定厚度才能形成自身稳定结构。
