砂土因为其高渗透性一直被认为是石灰桩加固的禁区,因为过多地下水的渗入会导致石灰桩“软心”。然而如果克服了这一缺点,石灰桩将是一种加固效果良好、造价低、噪音小和施工方便快速的砂土地基处理方法。本文将介绍一种行之有效操作简便的隔水帷幕法,用于解决较高渗透性土层中石灰桩的“软心”问题。 Because of its high permeability, sandy soil has long been considered a forbidden zone for the reinforcement of lime piles, as excessive infiltration of groundwater leads to lime piles. However, if this shortcoming is overcome, the lime pile will be a sand foundation treatment method with good reinforcement effect, low cost, low noise and quick construction. This article will introduce an effective and easy-to-use water curtain method to solve the “soft heart” problem of lime piles in higher permeability soil.
