A system includes a conduit, a sensor system and a controller. The conduit may be associated with a structure, having a portion thereof disposed on a surface, and being disposed in a direction normal to the surface. The controller is in communication with the sensor component. When the sensor system is operable to detect when sediment on the surface and surrounding the structure is removed from an area around the structure, an initial length, l.sub.i, of the conduit is disposed below the surface of the sediment on the surface and surrounding the structure at an initial time. When the sensor system is operable to detect when sediment is deposited around the structure, the initial length, l.sub.i, of the conduit is disposed above the surface at the initial time.

The invention relates to a method to test friction resistance at inner and outer sidewalls of pipe pile through in-situ test. The method comprises embedding a strain sensor at inner or outer sidewalls of pipe pile to measure strain variation generating on pipe pile body under the action of load; carrying out static load test with the soil plug remaining in the pipe pile to obtain the strain variation ε.sub.p1j,i of the pipe pile body at the i.sup.th soil layer; taking out the soil plug remaining in the pipe pile and carrying out static load test to obtain the strain variation ε.sub.p2j,i of the pipe pile body at the i.sup.th soil layer; and obtaining the friction respectively at the outer and inner sidewalls of the pipe pile at the i.sup.th soil layer according to the measured strain variation, ε.sub.p1j,i and ε.sub.p2j,i.

The present invention comprises a system for monitoring the angular movement of a structure's foundation, wall, beam and/or column with one or more monitoring devices in communication with either a local computing device (a hub) that displays the current angular deviation and direction from an initialized state, a remote server capable of generating a web page display of the current angular deviation and direction from an initialized state, or both. Additionally, the hub can be connected to the internet where data from the monitoring devices it is in communication with can be shared with a remote monitoring service, off-site server or both.

A soil stabilization system for a structure can include a stem wall and floor slab disposed within a perimeter of the stem wall. An aggregate base course (ABC) layer can be disposed within a perimeter of the stem wall and below the floor slab. A ventilation opening can extend to the ABC layer, and an air exhaust system can extend between the ABC layer and an exterior of the structure. A method of soil stabilization for a structure can include measuring a moisture content of an expansive soil below a structure, drawing dry air through the ABC layer and over a surface of an expansive soil. Moisture can be removed from the expansive soil into the dry air by evaporation to create moist air, and moist air can be evacuated at an exterior of the structure.
