要介绍强夯置换法及其适用范围。
答案
参考答案:
强夯置换法是采用在夯坑内回填块石、碎石等坚硬粗颗粒材料,用夯锤夯击形成连续的置换墩,由置换墩(在软粘土中)或置换墩与墩间土(在饱和粉土中,形成复合地基)承担上部结构传来的荷载。
强夯置换法适用于高饱和度的粉土与软塑—流塑的粘性土等地基上对变形不严的工程,在设计前必须通过试验确定其适用性和处理效果。

Different from popular thoughts, sometimes flu(流感) is not caused by bad weather. It is caused by viruses in the body. 51 , A/H1N1 flu has been spreading in the most parts in the world. Some studies have now shown that one of 52 ways of spreading the viruses is through the air when 53 A/H1N1 flu-sufferer coughs or sneezes. However, its viruses can sometimes spread by 54 . After a flu-sufferer rubs his nose, the viruses might be spread to his hand. Then a friend 55 to visit him, they shake their hands. The friend then gets something 56 by hand, and several days 57, he is infected. A child 58 is carrying A/H1N1 viruses uses tissues(面纸) to clean his running nose, although his parents pick up the tissues and carefully throw 59 away, they fail to wash their hands, and they will catch the viruses, too. So it is important for you to wash your hands often, it will stop the viruses from 60 in a way.
