为了消除软基的液化性,采用高真空击密法联合深层降水处理,通过对水位和沉降进行观测,分析了固结沉降规律,采用静力触探法对土体进行液化判别,计算了静力触探值和液化土层的厚度。结果表明:完全消除了场地内8m深度内土层的液化问题,基本消除了场地内8m以下深度的土层液化问题,提高了软土地基的承载力及稳定性,在节约了工程造价的同时改善了表层吹填土性,为类似工程提供了新的、有效的参考依据。
In order to eliminate the liquefaction of the soft foundation, the combination of high vacuum sealing and deep precipitation treatment was adopted. The water level and settlement were observed, the consolidation and settlement rules were analyzed, and the liquefaction of the soil was detected by static cone penetration method. Force touch value and liquefied soil thickness. The results show that the problem of liquefaction of soil layer within 8m depth is completely eliminated and the liquefaction of soil layer below 8m depth is basically eliminated and the bearing capacity and stability of soft soil foundation are improved. While the project cost is saved Improve the soil surface filling, providing a new and effective reference for similar projects.
