红层泥岩填料强夯地基的效果分析

Effect Analysis of Red Mudstone Filling Dynamic Compaction Foundation

强夯法是一种常规地基处理方法,但强夯处理的效果的检测通常较为困难。本文通过工程实例研究,在川西地区对红层泥岩填料强夯地基进行了密度试验、颗分试验、夯沉量观测、动力触探、载荷试验等多种手段的地基检,评价了强夯地基的效果。结果表明动力触探数据检能够较为快速测出强夯作用影响的深度和范围,评价场地地基的加固效果,可作为强夯试验的检测主要手段之一。

The dynamic compaction method is a conventional foundation treatment method, but the effect of the dynamic compaction treatment is usually more difficult. In this paper, through engineering case studies, the foundation detection of the dynamic compaction foundation of red-bed mudstone filler was carried out in the western Sichuan area, such as density test, particle fraction test, ramming and sediment observation, dynamic penetration, load test, etc., and the effect of the dynamic compaction foundation was evaluated. The results show that the dynamic penetration data can quickly measure the depth and scope of the influence of dynamic compaction and evaluate the reinforcement effect of the site foundation, which can be used as one of the main means for detecting the dynamic compaction test.
