A two-dimensional (2D) numerical analysis model was established by taking a pipe gallery deep excavation subject to asymmetric load as an example. The numerical analysis results were in good agreement with the measured data, thus verified the validity of the numerical model. On this basis, the stress and displacement of support structure caused by the change in foundation asymmetric load were studied. According to the numerical results, horizontal displacement of the diaphragm wall (DW) was dominant, and the maximum horizontal displacement of the DW was 7.54 mm when the deep excavation was completed. With the increase in asymmetric load, the left wall displacement continued to increase, while the displacement of the right DW continued to decrease, and the maximum horizontal wall displacement occurred near the excavation face. The DW was the main bending component, and the maximum wall bending moment when the deep excavation was completed was 173.5 kN\u00b7m. The maximum wall bending moment increased with the increase in asymmetric load, and the maximum wall bending moment on the left of the deep excavation was greater than that on the right. The inner support sustained the main component of axial force, with the axial force peaking at 1051.8 kN when the deep excavation was completed. The axial force of the inner support increased with increasing the asymmetric load, and the axial force of the second inner support was obviously greater than that of the first inner support. This research has a positive effect on the design and optimization of deep excavation support structure subject to asymmetric load on ground surface.<\/jats:p>","DOI":"10.3390\/sym16101309","type":"journal-article","created":{"date-parts":[[2024,10,4]],"date-time":"2024-10-04T04:49:02Z","timestamp":1728017342000},"page":"1309","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Mechanical Characteristics of Deep Excavation Support Structure with Asymmetric Load on Ground Surface"],"prefix":"10.3390","volume":"16","author":[{"given":"Ping","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Architecture and Engineering, Tongling University, Tongling 244000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Hydraulic Engineering, Anhui Water Conservancy Technical College, Hefei 231603, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhanqi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mining Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3435-7361","authenticated-orcid":false,"given":"Panpan","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Hefei University of Technology, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wang, Y., Guo, P., Lin, H., and Zhao, Y.
