...Xianfeng Ma, PhD; Guohang Tang, Eng; Mingyang Cao, PhD; Yuxiang Zou, Eng; Haihua Zhang, PhD This study presents a series of centrifuge model tests that were conducted to investigate the grouting mechanism and its effect during rectangular pipe jacking in soft soil. A new jacking grouting device...

...Ali Ghodrati, MSc; Mohsen Sabermahani, PhD; Asghar Habibnejad Korayem, PhD One of the most significant factors affecting the efficiency of jet-grouting operation is the diameter of the constructed column, depending on soil properties, stress state and operating parameters, including grout pressure...

...Mohsen Sabermahani, PhD; Seyed Rasool Soorani, MSc; Soheil Sharifi, MSc Jet grouting is a developing technology for soil improvement in most soil types. It offers advantages such as relatively short execution and a high volume of soil rehabilitation. Nonetheless, due to the complexity...
