Abstract: The present disclosure discloses an optical fiber sensing monitoring device for soil settlement and a settlement amount measurement method. The optical fiber sensing monitoring device includes a baseline rod that is internally hollowed. A plurality of settlement monitoring circular rings are sleeved outside the baseline rod, and are coaxial with the baseline rod; each settlement monitoring circular ring is provided with one trigger device that can spread an anchor by means of touching; the baseline rod is provided with through holes corresponding to the settlement monitoring circular rings; the trigger devices are provided with trigger sticks on the inner sides; and the trigger sticks extend into the baseline rod via the through holes.

Abstract: Embodiments of the present disclosure provide a test apparatus for pile-soil interface shear mechanical properties, comprising a support device, a pressure device, a membrane box, and a thrust device; wherein the support device comprises a bottom plate, a top plate, a support beam, and a plurality of bracing struts, the bottom plate and the top plate being both provided with a through-hole for inserting a model pile. The test apparatus for pile-soil interface shear mechanical properties according to the present disclosure has a simple structure and is easy to operate, which may accurately simulate mechanical properties of pile soils having different types of piled foundations in actual works, thereby facilitating researches on pile-soil testing.
