2) Influenced by ecological environment protection and relevant policies, the market supply of raw materials is insufficient, and the materials meeting the requirements generally need to break rock masses, so that adverse effects on the ecological environment can be caused;

3) The unfavorable material sources in the original site cannot be effectively reduced, the dam body design is designed to achieve the purpose of treatment by combining the material source amount on the site, the size of the dam body is possibly increased to enable the dam body to play a corresponding role, and the investment cost is high;

4) The difficulty of secondary material transportation is high and the cost is high under the influence of the conditions such as geological disaster site landform and road;

5) The strength of the masonry dam body is mainly influenced by the strength of the bonding mortar, and the masonry dam body is low in strength and easy to damage under the influence of external conditions.

Secondly), the concrete (reinforced concrete) solid dam body has the following 2 defects:

1) The commercial concrete and the steel bar are high in price, and the solid dam body is large in demand and high in cost;

2) The unfavorable material sources in the original site cannot be effectively reduced, the dam body is designed to achieve the purpose of treatment by combining the material source amount on the site, the size of the dam body is possibly increased to enable the dam body to play a corresponding role, and the investment cost is high.

In order to overcome the defects, the application provides a filled reinforced concrete box ballast dam.
