Rock anchor foundation can be widely used for the practical transmission line engineering in mountain areas. On strong-weathered sandstone ground, ten sets of uplift static load test of single rock anchor foundation were carried out. Based on the testing results, the typical failure modes and the ultimate uplift bearing capacity of foundations were obtained. Internal force distribution and effective anchorage depth were investigated through stain measurements. Design parameters of rock anchor foundation on sandstone ground were proposed, which can provide a reference for transmission line engineering design.

Line Engineering

Excavated foundation has widely used in the field of transmission line engineering because of its large capacity to resist uplift and moment force. Elastic-plastic numerical model were established by using the finite element software ABAQUS focusing on the difference of bearing characteristics of inclined and vertical excavated foundation. There is very slight difference of axial uplift resistances between the both foundations because almost the same soil mass are mobilized at the same displacement loading. However, failure modes and horizontal resistances of negative, positive and vertical foundations are very different. The larger soil mass along the shaft of negative foundation is mobilized than positive and vertical foundations. The uplift resistances of vertical and negative foundations are about 5% and 25% higher than positive foundation at horizontal displacement of 50mm respectively.

In recent years, the investment projects of overhead line engineering increase year by year. Establishing scientific cost prediction concept and optimizing cost prediction method can improve the investment utilization efficiency. Based on the actual cost data of 110kV overhead line project, this paper extracts the principal component factor through principal component analysis and eliminates the correlation between the original indicators. Then, the training sample is input into the least-squares support vector machine model to build a learning network. Finally, the predicted value of the model is compared with the actual cost level for analysis. The prediction results show that the average error rate is less than 5%, indicating that the PA-LSSVM model constructed in this paper can effectively predict the overhead line engineering cost.

There are various forms of foundation used in transmission line engineering, which can be divided into undisturbed soil foundation and non-undisturbed soil foundation according to the form of stress. In view of the geological condition that the upper layer has a thick overburden and the lower layer is rock, the composite bolt foundation is recommended to make full use of its upper undisturbed soil.
