Analysis of Test Pile Data of Bidirectional Dry Jet Mixing in Lianyungang Section of Lianyungang-Suqian Expressway
In Lianyungang,the marine soft soil is widely distributed with low bearing capacity,the foundation must be reinforced before carrying out construction on top of it.Taking the test section of the first phase of Lianyungang section of Lianyungang-Suqian Expressway using bidirectional dry jet mixing as the research object,the mix proportion of cement soil and on-site pile test data were analyzed,the comprehensive scoring method was used to evaluate the test pile effect,the feasibility of ce-ment content and other preset construction technical parameters was verified,and relevant suggestions and measures were put forward in combination with the test pile effect to improve the pile formation effect in the subsequent formal construction.
