The 10th session of the live broadcast series "My Technology, My Presentation" organized by the Foundation Engineering Academy was successfully concluded on June 27, attracting numerous experts, scholars, and participants in the foundation engineering field. The event was hosted by Yang Shenggui, Chief Engineer of Jianyan Foundation Engineering Co., Ltd., with Chen Wei, a senior engineer at the company, as the keynote speaker. The event focused on improved models for foundation treatment engineering calculations under complex foundation outlines and complex foundation reaction forces, sparking keen interest in related technical fields within the industry.

Jianyan Foundation Software was developed by Jianyan Foundation Engineering Co., Ltd. (formerly the Foundation Institute of the China Academy of Building Research), the chief editor of multiple national and industry standards for foundation engineering. After years of accumulation, it has been successfully applied to numerous complex engineering design projects. In December 2019, the software was evaluated by the Science and Technology and Industrialization Development Center of the Ministry of Housing and Urban-Rural Development and recognized as having reached the domestic leading level, making it a trusted professional tool in the foundation engineering field.

From a theoretical perspective, the construction of foundation pit engineering usually requires step-by-step excavation, installation of supports and pre-stressing, followed by the removal of support structures, making the construction process relatively complex. In addition, some more complex excavation methods (such as counter-pressure earth berm basin-style excavation) also exist. Since the calculation process must simulate the actual construction conditions of the foundation pit, the complexity of the calculation increases, which in turn complicates the judgment of results. Some complex support structures (such as H-shaped double-row piles) and complex excavation methods (such as basin-style excavation) are not covered in detail in current foundation pit engineering industry standards or local standards, but many successful application practices already exist, so the corresponding calculation models need to be explored in depth. During the event, the keynote speaker discussed the importance of calculation models for actual complex foundation pits and foundation treatment engineering that are not clearly specified in existing codes. These discussions covered several calculation model issues, including counter-pressure earth berms inside foundation pits, non-standard double-row piles in foundation pits, user-defined forces in foundation pits, and displacement and settlement of composite soil nail walls considering anchor pre-stressing. The development of these models not only attracted the attention of peer experts but will also bring significant economic and social benefits to complex engineering design, contributing new ideas and methods to the progress and development of the foundation engineering field.

Through careful study and analysis of detailed engineering cases, Engineer Chen conducted in-depth discussions on foundation pit data. Through meticulous observation and data mining, he comprehensively evaluated the geological conditions, support structures, and construction processes of the foundation pit, and proposed effective solutions and optimization suggestions. Engineer Chen's analysis not only provided strong support for the design and construction of foundation pit engineering but also brought new inspiration and development directions to research and practice in related fields. His in-depth research provided important references for the safety, efficiency, and reliability of foundation pit engineering, contributing valuable experience and insights to industry development and engineering practice.

The "My Technology, My Presentation" live broadcast series has become an important platform for exchange and sharing among experts and scholars in the foundation engineering field, promoting the widespread application of Jianyan Foundation Software calculation models in actual engineering and adding new vitality and momentum to the development of foundation engineering. The holding of the event provides opportunities for continuous exploration and innovation within the industry, helping the foundation engineering field achieve greater progress in technology and practice and promoting the vigorous development of the field.
