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.

Construction Practice

Based on the construction practice of strengthening dam foundation and cross-strait dam end (0+149～0+330) high pressure jet grouting impervious wall of an earth dam, this paper expounds the construction equipment, technological process, construction parameters and construction method of high pressure jet grouting impervious wall construction. By analyzing the impervious wall’s depth, continuity, strength, permeable rate, the quality of the wall is eligible, and its indexes comfort the design requirements. The experiences are useful in similar earth dam reinforcement construction.

Good Agreement

Ordered porous copper with elongated pores has been fabricated by a continuous unidirectional solidification method in a hydrogen gas atmosphere with high pressure. The porosity of the ordered porous copper is significantly affected by the pressure of hydrogen. A theoretical model is developed to get the relation between the porosity and the processing parameters. The calculated values are in good agreement with the experimental results. Key words: Unidirectional solidification; Ordered porous copper; Porosity; Modeling.
