This procedure is applicable to the calculation of three-phase short circuit of high-voltage network in various small and medium-sized projects. The program uses the node potential method to establish the admittance augmentation matrix, which can be solved to obtain the node potential, voltage drop and current of each branch. Then, according to different power supply types, the short circuit current flowing through each branch can be calculated by using the operation curve method of constant voltage (power grid) or unit (steam turbine generator and water turbine generator). The number of network branches or nodes cannot be more than 50. The function of large capacity motor near the short circuit point has been taken into account.

Small and medium-sized Analysis on the current situation of water conservancy project construction supervision
At the present stage, the construction supervision of small and medium-sized water conservancy projects in China is mainly the supervision during the construction period. After the supervision unit accepts the commission, the project construction is about to start. The supervision personnel are not very familiar with the environment and design drawings, and have no in-depth grasp and familiarity with the project. They need to be familiar with the situation while working. However, water conservancy projects are relatively large in scale, relatively complex in technology, long in front, poor in construction environment and many influencing factors, which are not conducive to the smooth implementation of supervision work. During construction, supervisors will encounter the following various impacts from different units and their own shortcomings. How to deal with and overcome these contradictions is also a yardstick to test the work level and ability of supervisors.

Small and medium-sized Treatment method of bridge and culvert soft foundation
When the road route encounters obstacles such as rivers, lakes, deep valleys and other routes, various types of bridge (beam), culvert (tunnel) structures must be built to maintain the continuity of the road and give full play to its normal transportation capacity. The Technical Standards for Highway Engineering issued by the Ministry of Communications stipulates that medium and small bridges and culverts should follow the direction of the route, so the position of bridges and culverts cannot be changed at will. When building bridges on soft soil foundation, the more troublesome problem encountered is the lack of bearing capacity of natural foundation. However, the bridge foundation requires that the foundation should have sufficient bearing capacity to meet the required settlement deformation,. When the foundation is buried 25cm below the freezing line and 1m below the scouring line, in case of soft foundation, in order to ensure that the bearing layer has sufficient strength and that the medium and small bridges will not be inclined and damaged due to uneven settlement, in addition to the correct design (light piers and abutments are often used, such as buttress, embedded abutment and column pier), reinforcement measures should also be taken for the soft foundation.
