摘要
当预制管桩沉桩于淤泥质粉质粘土中时,基槽开挖会损伤桩身,可采用粉体搅拌法(简称干法)对地基进行加固,再施工预制管桩做基础。这种方法具有造价低、施工速度快和质量可靠的特点,在工程上得到广泛应用。
When prefabricated tubular pile is inserted into silty powder clay and excavation of foundation trench could damage pile body,the foundation may be reinforced by powder mixing method(also called dry method for short) before processing of prefabricated tubular pile as foundation.This method has many characteristics,such as low construction cost,fast construction speed and reliable quality,etc.,enjoying comprehensive engineering application.
