【摘要】：采用真空預(yù)壓法加固新近吹填的超軟土地基時,盡管地基沉降量很大,含水率也有大幅度的降低,但有時加固后表層土的十字板剪切強(qiáng)度仍然較低,不能滿足工程需要。這主要是由于這類土顆粒中黏粒甚至膠粒的含量較大且土的固結(jié)快剪內(nèi)摩擦角較小所造成的。對于真空預(yù)壓后不能滿足工程需要的表層土,可進(jìn)一步采用戧灰拌合的方法進(jìn)行處理。
[Abstract]:When using the vacuum preloading method to reinforce the newly filled ultra-soft soil foundation, although the settlement of the foundation is very large and the moisture content has been greatly reduced, sometimes the shear strength of the cross plate of the surface soil is still relatively low, which can not meet the engineering needs. This is mainly due to the large content of clay and even colloidal particles in the soil particles and the smaller internal friction angle of the consolidation quick shear of the soil. For the surface soil which can not meet the need of engineering after vacuum preloading, the cement mixing method can be used to deal with it further.
