Abstract

This is a measure for reduce load on the EPS plates in covertly-up structure members (for example the culvert). 1) To define the strength intensity and thickness of EPS plate on the top of culvert according to the 1 / 2-1 / 3 pressure data of filled soil cylinder to define the thickness of it according the 2%-6% height of the culvert above the ground, for the pile based culvert according the practice condition. To define the strength intensity for use to side may be in accorded with the 1 / 2-1 / 3 value for use to the top. 2) To reduce load measures of the plane structure members use to the hole's side, adopt the calculate formula of horizontal pressure of soil cylinder, and for the members use to hole's top don't adopt the formula of pressure of soil cylinder.

Description

technical field

[0001] The invention relates to the technical field of geotechnical engineering. Applicable to all kinds of buried structures in highways, railways, water conservancy, electric power, mining, municipal, petroleum, military and other departments, such as culverts, culverts, and tailgates under embankments and canal embankments for pedestrians, traffic, drainage, etc. Flood discharge tunnels under mine dams (reservoirs), corridors and drainage tunnels under earth-rock dams, buried underground substations, various underground passages and weapon shelters, etc. Background technique

[0002] Culverts (pipes) are top-buried structures, and they are also one of the "lifeline projects" known internationally today. It is widely used in transportation, water conservancy, railway, mining, electric power, municipal, petroleum, military industry and many other departments.

[0003] With the rapid development of high-grade highway construction in our country, the stress,...
