详细介绍了高真空击密法的原理及施工控制要点。通过工程实例,以浅层平板载荷及重型动力触探检测结果和沉降观测数据为依据,证明高真空击密处理软土地基有工期短、效果好等优点,在一定意义上将强夯法推广应用到了饱和软粘土。

The paper gives a detailed introduction to the theory of the high vacuum and dynamic compaction method and the key points of application of the method to engineering practice.Based on the construction practice,the results of the shallow loading plate tests and the heavy duty dynamic sounding as well as the measured data of settlement prove that the method of high vacuum preloading in combination of dynamic compaction to improve soft soil foundations has the advantage of short working duration and better improvement effect,which has to some extent applied the dynamic compaction method to the saturated soft clayey soil.
