主要是由高镀锌钢丝或热镀铝锌合金钢丝编织而成的箱笼，内填石料等不风化的填充物做成的工程防护结构。石笼内抛填厚度为0.2-0.4m的块石，块石下设厚度为10-20cm的砾石层以利于排水和减少土壤流失。
Mainly by high galvanized steel wire or hot-dipped aluminum-zinc alloy steel wire woven into the cage, filled with stone and other non-weathering filler made of engineering protection structure. The stones with thickness of 0.2-0.4 m were thrown into the cage, and the gravel layers with thickness of 10-20 cm were under the stones to facilitate drainage and reduce soil loss.
优点：
Advantage:
具有很好的柔韧性、透水性、耐久性以及防浪能力等优点，而且具有较好的生态性。
It has the advantages of good flexibility, water permeability, durability and anti-wave ability, and has good ecological characteristics.
由于石笼的空隙较大，因此能在石笼上覆土或填塞缝隙，以及微生物和各种生物，可实现多年生草本植物自然循环的目标。
The natural circulation of perennial herbaceous plants can be achieved by covering the stone cage with soil or filling gaps, as well as by microorganisms and various organisms because of the large gaps in the stone cage.
主要用作河道、岸坡护坡。
It is mainly used for river bank and bank slope protection.
缺点：
Shortcomings:
网格外露，金属的腐蚀、塑料网格的老化、合金的性能等问题。
Grid exposure, corrosion of metals, aging of plastic grids, and properties of alloys.
以及外露网格的局部容易被破坏，网内松散的石头容易掉出网外，是影响这类挡土墙安全的重要因素。
And the exposed mesh is easy to be destroyed, loose stones in the mesh are easy to fall out of the mesh, which is an important factor affecting the safety of this kind of retaining wall.
另外，金属、合金网格的切断端部非常尖锐，亲水活动和攀爬自救的人容易被伤害。
In addition, the cutting ends of metal and alloy grids are very sharp, and people who are hydrophilic and climbing to save themselves are vulnerable to injury.
