Through a comparison between several treatment methods such as drainage consolidation , powder spraying , pressure mud pumping , gyratory spray pumping etc , the result shows that under suitable condition the application of gyratory spray pumping has some advantages such as short construction period , high ground base bearing force after treatment and less compressibility . it can guarantee structures to be built in due time and safety after completion . those results show that gyrayory spray pumping technology has good practicality inengineering 通过对排水固结法、粉喷法、压力注浆法、旋喷注浆法等几种应用处理方法的效果对比，表明旋喷注浆法处理地基在适宜的条件下应用，具有工期短、处理后地基承载力较高、压缩性较小的优点，能保证构造物按期施工及其建成后的安全使用，只有较高的实际应用价值。
