Construction method of cast-in-situ bored pile in karst development area
The invention relates to the technical field of civil engineering, in particular to a karst development area cast-in-situ bored pile construction method which comprises the following steps: based on construction position information, collecting electromagnetic wave data of a target area at multiple angles and depths, and recording rock layer, karst cave and crack data to obtain geological data of the target area. According to the method, a data basis is provided for geological three-dimensional model construction by utilizing electromagnetic wave data and identifying a rock layer, a karst cave and a crack, the prediction precision of the model is improved by simulating the response of karst, a fault and a soft soil layer to a structure, and the prediction accuracy of the model is improved by combining the evaluation of chemical erosion and physical erosion effects of a target karst development area on the cast-in-place pile. The long-term influence of the environment on the pouring material is predicted, the stability and safety of the structure are improved, the long-term sustainability of a target engineering project under the karst complex geological condition is ensured, and the scientificity and efficiency of construction planning are improved by combining drilling position analysis and construction path planning.
