　　In the short term, due to the further increase in raw materials such as iron ore, the cost of steel prices has risen, and steel mills may slightly raise prices to stabilize profits. From today's market outlook, futures prices are still trying to break through the medium-term resistance level of 4750. However, after opening high and moving high at night, the overall trend today is mainly high volatility, without forming a strong breakthrough. In the short term, it will drive an upward trend, but whether it can form an upward trend still depends on whether the prices in the next two days can stand above the resistance level. However, based on the fundamental news of the market, supply and demand are still weak, and the positive news is a medium - to long-term influencing factor with limited short-term impact. After the year, it may drive prices up. Overall, steel prices will rise slightly tomorrow, and there will still be intense long short games in the medium term. It is recommended to observe the situation for two days.

　　Principles for Layout of Settlement Observation Points

　　According to the requirements of DGJ32/J18-2006 "Observation Methods for Building Settlement" and JGJ8-2007 "Code for Deformation Measurement of Buildings", settlement observation points should be set up at locations that can comprehensively reflect the deformation characteristics of the building foundation, and small manholes should be built for protection. They should be selected at the following locations:

　　A、 At the four corners, major corners, and every 10-15 meters along the exterior wall or every 2-3 column bases of the building;

　　B、 On both sides of the intersection of high and low rise buildings, old and new buildings, longitudinal and transverse walls, with different geological conditions, load distributions, foundation types, foundation burial depths, upper structures, building cracks, post pouring belts, settlement joints, and expansion joints, as well as the boundary between artificial and natural foundations and the boundary between filling and excavation;

　　C、 For buildings with a width greater than or equal to 15 meters, or with a width less than 15 meters but complex geological conditions and expansive soil areas, internal wall points shall be set on the load-bearing inner partition (longitudinal) walls, as well as at the buildings, elevator shafts, and central shafts of frame, frame shear, frame tube, and tube in tube structural systems;

　　D、 At the four corners and middle positions of raft foundation and box foundation;

　　E、 Multi story masonry buildings have a vertical wall spacing of 6-10 meters at the corresponding end of the horizontal wall;

　　F、 On each or part of the column foundation of the frame structure building or along the axis of the longitudinal and transverse walls, as well as adjacent column foundations where significant uneven settlement may occur;

　　G、 The ends of high-rise buildings correspond to both horizontal and vertical directions;

　　H、 Adjacent to heavy objects, areas significantly affected by vibration, and hidden banks (ditches) under the foundation;

　　I、 The corners of heavy equipment foundations and power equipment foundations, changes in foundation form or burial depth, and changes in geological conditions on both sides;

　　J、 For high-rise structures such as TV towers, chimneys, water towers, oil tanks, oil refining towers, blast furnaces, etc., they should be located at symmetrical positions along the perimeter that intersect with the foundation axis, with no less than 4 points.
