High-pressure jet grouting pile is a kind of stratum reinforcement technology developed in recent years. Due to its characteristics of high solid strength, fast construction, low noise, safety and reliability, low cost, controllable reinforcement diameter, strong adaptability to stratum, and good reinforcement effect for soft soil, loose soil and water-rich stratum, high-pressure jet grouting pile technology has been more and more widely used in foundation treatment, water stop, and seepage prevention, tunnel lining and other fields in recent years. As a country with a relatively late development of underground construction engineering, Vietnam has little research on special geotechnical reinforcement technology, especially on special geotechnical reinforcement technology around urban underground construction engineering, especially on its theoretical analysis and practical application. Therefore, this thesis combines the Vietnam Trung Hoa tunnel project as an example, using the theoretical calculation formula and field monitoring measurement comparing the two methods, the high pressure jet grouting pile system research in Vietnam in the underground engineering reinforcement principle and application effect, get to the actual engineering design and construction has a guiding significance to the research, provides the reference for future similar projects. Finally, the application effect of high-pressure jet grouting pile in underground building reinforcement project is evaluated, which proves that high-pressure jet grouting pile has good applicability and economic benefit in underground building reinforcement project in Vietnam.

The interaction of piles with different lengths and the grillage in the foundations of high-rise buildings is considered. The numerical modeling of the «base – foundation – superstructure» system is performed. The redistribution of the efforts in piles depending on the sizes of a foundation slab and the parameters of piles (length and location) is investigated. Typical zones of a foundation such as central, lateral, and angular ones are separated. The redistribution of efforts between piles and a grillage is revealed.

W pracy rozważa się wzajemną interakcję pali o różnej długości i rusztów w fundamentach budynków wysokich. Wykonano analizę numeryczną systemu "grunt - fundament - budynek". Analizowana jest redystrybucja wykorzystania nośności poszczególnych pali w zależności od wymiaru płyty fundamentowej i parametrów pali (długość i położenie). Wydzielone są typowe strefy fundamentu - centralna, boczne i kątowe. Sprawdzone redystrybucję wytężenia pomiędzy palami a rusztem.

The basic characteristics of piles with base expanded by jet grouting and the results of experimental pile tests were presented. The main advantage of the expending is increasing the pile bearing capacity by as much as 200% in suitable circumstances. Conditions applicable for the implementation of the proposed technology to the practice of engineering were discussed.
