加大截面加固法：加大截面加固法即采取增大混凝土结构或构筑物的截面面积，以提高建筑物的承重力并且可以满足正常使用的一种加固方法。该工程用于此类构件和一般构筑物的加固，优缺点显而易见，其优点为施工工艺简单、适应性强，且使用经验丰富；其缺点是施工的湿作业时间长，在混凝土养护期间需要严重限制载荷，否则很容易导致混凝土变形，导致承载能力下降，且加固后会造成结构自重增大、建筑物的使用空间减小等问题.<br>置换混凝土加固法:该法的优点与加大截面加固法较为接近，而且加固后不会影响建筑物的净空，但与此同时，同样存在施工的湿作业时间长的缺点；此法适用于受压区混凝土强度偏低或有严重缺陷柱等混凝土承重构件的加固。<br>有粘结外包型钢加固法：该法也称湿式外包钢加固法，此法优点为受力可靠、施工简便、工作量较小，但用钢量较大，且不宜在无防护的情况下使用，用于600摄氏度以上的高温场所；适用于使用上不允许显著增大原构件截面尺寸，但又要求大幅度提高其承载能力的混凝土结构加固。<br>粘贴钢板加固法：该法施工快速、现场基本无湿作业或仅有抹灰等的少量湿作业，对生产和生活影响小，且加固后对原结构外观和原有净空基本没有显著影响，但是其加固效果在很大程度上取决于胶粘工艺与操作水平；适用于承受静力作用且处于正常湿度环境中的受弯或受拉的构件的加固。<br>粘贴纤维增强塑料加固法：此法除具有粘贴钢板相似的优点外，还具有耐腐浊、耐潮湿、几乎不增加结构自重、耐用、维护费用较低等优点，但需要专门的防火处理，避免产生火灾或结构变形，适用于各种受力性质的混凝土结构构件和一般构筑物。<br>绕丝法：该法的优缺点与加大截面法相近；适用于混凝土结构构件斜截面承载力不足的加固，或需对受压构件施加横向约束力的场合。<br>锚栓锚固法：该法适用于混凝土强度等级为C20~C60的混凝土承重结构的改造、加固；不适用于已严重风化的混凝土结构及其他轻质结构。

Enlarging section reinforcement method: enlarging section reinforcement method is a reinforcement method which can increase the section area of concrete structure or structure to improve the bearing capacity of building and meet the normal use. The advantages and disadvantages of this project are obvious when it is used for the reinforcement of such components and general structures. Its advantages are simple construction technology, strong adaptability and rich experience in use. Its disadvantages are long wet operation time of construction and severe load restriction during concrete maintenance. Otherwise, it is easy to cause concrete deformation and decrease bearing capacity, and the self weight of the structure will increase after reinforcement Large, the use of building space reduction and other issues<br>Replacement concrete reinforcement method: the advantages of this method are close to the method of increasing section reinforcement, and the reinforcement will not affect the clearance of the building, but at the same time, there is also the disadvantage of long construction wet operation time; this method is applicable to the reinforcement of concrete bearing components such as columns with low concrete strength or serious defects in the compression area.<br>Bonded external steel reinforcement method: this method is also called wet external steel reinforcement method. The advantages of this method are reliable stress, simple construction and small workload, but the amount of steel used is large, and it is not suitable to be used without protection. It is suitable for high temperature places above 600 ℃; it is not allowed to significantly increase the section size of the original component in use, but it is also required to greatly improve its bearing capacity Concrete structure reinforcement.<br>Paste steel plate reinforcement method: this method is fast in construction, has little impact on production and life, and has no significant impact on the appearance and original clearance of the original structure after reinforcement, but its reinforcement effect largely depends on the adhesive technology and operation level; it is applicable to bear static force and in normal humidity environment. Reinforcement of members in bending or tension.<br>Paste fiber reinforced plastic reinforcement method: this method not only has the similar advantages of paste steel plate, but also has the advantages of corrosion resistance, moisture resistance, almost no increase in structural self weight, durability, low maintenance cost, etc., but it needs special fire prevention treatment to avoid fire or structural deformation, which is suitable for all kinds of stressed concrete structural members and general structures.<br>Wire winding method: the advantages and disadvantages of this method are similar to those of enlarging section method; it is suitable for the reinforcement of concrete structural members with insufficient bearing capacity of inclined section, or the occasions where the compression members need to be imposed with lateral binding force.<br>Anchor bolt anchoring method: this method is applicable to the transformation and reinforcement of concrete bearing structure with concrete strength grade of C20 ~ C60; it is not applicable to the seriously weathered concrete structure and other lightweight structures.<br>
