t is easy to cause the Yangtze River embankment soil of slip even collapse to have a deep foundation pit construction adjacent to the Yangtze River outsideembankment,there are a lot of risk. In this paper, a new combining technique of construction for large caisson is presented. Based on the construction environment, theconstructiontechnology,the smaller earthwork excavation of deep high pressure rotary jet grouting pile with undrained caisson combined construction technology combined with monitoring data for the open caisson excavation control is adopted. It has achieved relatively good results and summarized the advantages of deep high pressure rotary jet grouting pile with undrained caisson combined construction technology in engineering application owing the reference value for engineering applications.

It is easy to cause Yangtze River embankment soil slip or even collapse to have a deep foundation pit construction adjacent to Yangtze River outside embankment，with lots of risk . A new combined construction technique for large caisson is presented. The construction technology, the earthwork excavation of deep high pressure jet grouting pile combined with undrained open caisson construction technology, with data monitoring for the open caisson excavation control is adopted. This study mainly summarizes the advantages of deep high pressure jet grouting pile combined with undrained caisson combined construction technology engineering application, and describes the process of the combined construction and measures of deviation correction.The new combining construction technique has made a relatively effective protection for the Yangtze River levee and its ecological environment,having great engineering application value to some similar engineering.

Wide Range

High pressure jet grouting piles have a wide range of application in the engineering field. However, nowadays the increasing construction depth leads to an increasing difficulty of construction,which involves that the quality of construction is much more difficult to control. In this paper, some examples are given of the Luoyuan ultra-deep high pressure jet grouting piles. These examples are described with the used construction quality control methods and preventive recommendations for work construction quality detection methods. That is why this paper has an important guiding significance for similar projects.

Based on the experimental study of rotary filling piles with large diameter subjected to axial load in deep soft soil, the bearing capacity behavior and load transfer mechanism were discussed. Results show that in deep soft soil foundation, the super–long piles behave as end-bearing frictional piles. The exertion of the shaft resistance is not synchronized. The upper layer of soil is exerted prior to the lower part of soil. Meanwhile, the exertion of shaft resistance is prior to the tip resistance. For the different soil and the different depth of the same layer of soil, shaft resistance is different.
