摘要
在人工挖孔桩的桩端持力层采用压力灌浆可大幅度提高承载力，减小桩基础的埋置深度，且无噪声、无振动、无污染，设备简单，施工方便，因此可节省投资，缩短工期。
The adoption of pressare grouting bored pile technology would greatly promote pile's bearing capacity and reduce pile's embedded depth.Besides, it holds some other advantages such as noiselessness, non-vi bration, non-pollution, simple equipment and easiness in constrution. Above all,it is saving in cost of construction and shortening in construction schedule.
