Anti-epidemic traditional Chinese medicine health products are in line with the Healthy China strategy, play an important role in epidemic prevention and control, with adantages of diverse types, obvious effects, easy acceptance, and convenient administration. With rapid progess in science and technology, the research and development of new products is increasing and getting closer to the actual needs of different groups and different scenarios. With the rapid expansion of health industry of antiepidemic traditional Chinese medicine, while bringing more products to meet the needs of the public, it also fully exposes its shortcomings. This paper reviews its application and research and development status, and proposes suggestions and countermeasures for some of the existing problems, with a view to assisting the application and research and development of traditional Chinese medicine health products industry.

Based on the in situ observation and numerical simulation， the deformation characteristics of the retaining structure of a deep excavation and the existing building were investigated. According to the in situ observations and available literatures， parametric studies were conducted using FEM to investigate the deformational behaviors of the excavation adjacent to existing building. The relationships between the deformation of the retaining structures and the settlement of the adjacent building under various construction conditions were fully revealed. Results showed that the tieback anchored pile wall has a good deformation control capacity and can be applied effectively in Jinzhou area. The corner effect of the rectangular excavation is significant with a plain strain ration (PSR)of about 0.4~0.6.The linear relationship between the average building settlement (δva) and the maximum horizontal deformation of the retaining structure (δhm) is slightly influenced by the existing foundation depth and the excavation depth. The discreteness of δva and δhm appears when the distance between the building and the retaining structure (L) changes， however the δva/δhm decreases gradually with the increase of L.

Under the engineering background of anchored pile supporting excavation in sand layers， numerical models were established using the FEM program Plaxis to simulate excavations under two local anchor failure conditions of one-row and two-row anchor cable failures. The effect of prestressed anchor failures on mechanical response of retaining structures was studied. Besides， the load transfer response to the anchor failures was revealed. The results obtained from the numerical simulations show that the influence of two-row anchor cable failure on deformation and internal force of retaining structure was larger than that of one-row anchor cable failure. Under the most unfavorable condition of group anchor failures， the bending moments and displacements of retaining piles were 1.66 and 1.74 times of those under the normal construction condition， respectively， and the increase ratio of the bending moment of the retaining piles was the crucial determining factor of the piles failure.

STS (steel tube slab) method was used to construct the Olympic sports center station of Shenyang subway line 9. By field test of the steel pipe jacking， the vertical deformation of ground surface and pipe-jacking force were measured， and their changing laws during jacking were analyzed based on the monitoring data. The ground surface deformation laws in the cross section during jacking were summarized and the changing laws of ground surface deformation with the increase of jacking distance， along with the deformation mechanisms were analyzed. The pipe jacking force estimation method based on the filed mornitoring data is suitable for the strata in Shenyang， and could be used as an important reference to the application and development of STS method.
