振动水冲法已广泛地用于加固松软地基,但应用于松砂坝壳的加固这还是初次尝试。试验表明,振动水冲法加固松砂坝壳,既安全、可靠,又简便、经济。因而是一个良好的抗震加固措施。标准贯入试验是检验振冲加固效果的重要手段之一。加固试验中曾做了大量的标贯,由于种种原因,试验结果分散性较大。然而,这些现场资料的取得确实来之不易,也是十分宝贵的。文献对标贯试验已作了介绍。这里仅就标贯击数同平均有效压力及振冲桩距的关系作进一步分析,并提出相应的经验关系式。显然,从一个工程实例中得到的经验关系式是不成熟的,何况试验结果分散性又较大,而且,由于条件所限,试验组合嫌少,有的只能根据一、二个数据点加以推论。因 Vibratory flooding has been widely used to reinforce soft foundations, but it is still the first attempt to apply it to the reinforcement of loose sand dam shells. Tests have shown that vibrating water rushing to reinforce loose sand dam shells is safe, reliable, simple and economical. It is therefore a good measure of seismic strengthening. The standard penetration test is one of the important means for verifying the vibratory reinforcement effect. In the reinforcement test, a large number of benchmarks were performed. Due to various reasons, the test results were highly dispersive. However, the acquisition of these on-site data is indeed hard-won and very valuable. The literature has introduced the standard test. Here only further analysis is made on the relationship between the number of standard shots and the mean effective pressure and vibratory pile spacing, and corresponding empirical relationships are proposed. Obviously, the empirical relationship obtained from an engineering example is immature, not to mention the dispersiveness of the test results, and due to limited conditions, the experimental mix is ​​too small, and some can only be based on one or two data points inference. because
