深厚淤泥控制加载爆炸挤淤处理质量综合检验研究

         

摘要

首先分析了深厚淤泥爆炸挤淤围堤施工中的问题,然后评价目前已有的挤淤质量检验方法,提出了自沉沉降监测法,最后综合利用各种检验方法对一工程进行检验。通过研究发现,体积平衡法简单易行;钻探检测法是最直观最可靠的方法,但花费较高;物探检测法效率高,需结合钻探检测法实施,但在海水中不宜采用;自沉沉降监测法是一种间接方法,实施简单,花费较低。钻探检测法发现本工程围堤除少数标段泥石混合层厚度超过2.5m外,多数标段的挤淤质量良好。%The problems in deep mud treatment by explosive compaction in embankment construction was analyzed firstly, then the currently available methods to inspect the quality of explosive compaction were evaluated, and a method called settlement observation method was proposed, and finally the quality of an explosive compaction project was inspected comprehensively by various methods. The study found that the volume balance method is simple; drill testing method is most reliable but expensive; geophysical detection method is efficient, and the implementation needs to be combined with drilling, but should not be used in seawater; settlement observation method is an indi- rect method which is simple and less expensive. Drilling inspection found that except fir a short distance of embankment with stone - mixed - mud layer thickness that more than 2.5m, the majority shows good quality.
