| Abstract: |
According to the geological characteristics of the deep soft overburden and high pressurized water where the anchor of the 2300 meters suspension bridge is located, the safety risk analysis of the diaphragm wall anchorage foundation with rectangular-ambulatory-plane was carried out, and the risk sources were sorted out. The risk levels of each risk source were evaluated by expert questionnaire, and the risk levels of anchorage were analyzed by Kent index method. The countermeasures of all risk sources were formulated, and the main risk factors were studied. On this basis, the design scheme of anchorage foundation was optimized, the key control measures of risk factors in the construction process were put forward, and the corresponding emergency plans for main construction risks were formulated, which provided a guarantee for the smooth implementation of anchorage foundation scheme. |
