A method for inhibiting erosion at a coastal location includes inducing coastal vegetation to take root in a site-compatible mat including a biodegradable mat combined at most with fertilizer, sand, and/or soil. After the coastal vegetation has taken root in the site-compatible mat, the mat is placed on the coastal location, and the coastal vegetation is allowed to take root as the biodegradable mat decomposes. In embodiments, the coastal location can be a flat area of sand, or a constructed or naturally occurring sand dune. The site-compatible mat can include fertilizer and/or coir, which can be brown coir. The mat can include and/or be covered by sand or soil having a composition that is substantially equivalent to sand or soil that is indigenous to the coastal location. Bird roosting stakes can be planted through the mat.

A multi-objective optimized evaluation method of anti-seismic performance of a slope reinforced by a pile-anchor system is provided. The method includes: training an initial three-dimensional slope numerical calculation model to obtain an target three-dimensional slope numerical calculation model; determining numerical values to be imported into the target three-dimensional slope numerical calculation model according to deformation differences, to obtain a model analysis result; obtaining a simulation operation result according to a reinforcement scheme working condition table of the pile-anchor system; based on the model analysis result and the simulation operation result, evaluating anti-seismic reinforcing performance of the pile-anchor system to obtain comprehensive evaluation values, and then optimizing and evaluating the reinforcement schemes of an overall slope to be reinforced.

The provided are a device and method for measuring a bonding strength between a contaminated rock surface and a solidified material. The device includes a fixing and measuring assembly and four rock slabs enclosing a rectangular prism, where outer surfaces of the four rock slabs are fitted to two transverse support plates and two longitudinal support plates, respectively; the two longitudinal support plates are arranged between the two transverse support plates; upper and lower ends of the rock slabs are provided with an upper cover and a bottom plate, respectively; the upper cover and the bottom plate are detachably fixed to the two transverse support plates, respectively; the two transverse support plates are detachably fixed to each other through a second screw; a hydraulic device is provided among the four posts; and a movable end of the hydraulic device is provided with a supporting airbag.

To provide a common-use rockfall protection and avalanche prevention fence which can efficiently absorb the energy of rockfalls and which is more suitable as a protection fence having both functions of rockfall protection and avalanche prevention.

A common-use rockfall protection and avalanche prevention fence includes terminal struts installed at both ends; a plane member fixed to the terminal struts and deployed between the terminal struts; an intermediate strut disposed between the terminal struts; and an attachment wire net for fixedly attaching the plane member to the intermediate strut, a breaking load of fixing of the attachment wire net being smaller than a breaking load of the plane member.

A method for improving an inwards stability of an existing levee including a landslide slope (128) and at least one of a landside berm (132), a landside heel, and a landside trench. The method comprises placing columns (160) through the landside berm into one or more soft soil layers (40) with corresponding soil volumetric weights (s), wherein the columns have a column volumetric weight (c) that is at least 10% larger than the soil volumetric weights, and wherein the columns comprise a mineral aggregate and an impermeable filler.
