Embodiment Construction

[0039] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0040] At present, the commonly used landslide test platforms at home and abroad are mostly two-dimensional in size, and most of them adopt one-stage type. In order to simulate the characteristics of the actual slope-rock-soil interface with steep slopes and slow slopes, the landslide physical model experimental device of the present invention adopts a segmented and adjustable design concept.

[0041] Such as Figure 1~2 As shown, the landslide physical model experimental device of the present invention includes: a landslide test tank, which includes a base 11 and four sections of platforms, wherein the first section platform 1 is located on the base 11, and the first section p...

Abstract

The invention discloses an experimental device with a physical landslide model. The experimental device comprises a landslide experiment tank which comprises a base and four segments of platforms, wherein the first segment of platform is located above the base, the first segment of platform, the second segment of platform, the third segment of platform and the fourth segment of platform are connected in sequence, the first segment of platform is horizontal, and the inclination angles of the second segment of platform, the third segment of platform and the fourth segment of platform are adjustable. The experimental device with the physical landslide model disclosed by the invention has the characteristics of large scale, sectional type, multi-factor and overall process, and can truly simulate the overall damage evolution process of a landslide disaster chain under hydrodynamic force induction factors.

Description

technical field [0001] The invention relates to the field of landslide experiments, in particular to a physical model experiment device for landslides. Background technique [0002] In terms of the development of the landslide physical model experiment platform, foreign Wang Gonghui (2003) developed a landslide model experiment platform with a length of 1.8m, a width of 0.24m, and a height of 0.15m, and carried out model experiments under rainfall conditions. different slope failure modes were obtained; Sergio D.N.Lourenco (2006) developed a landslide model experiment platform with a length of 3m, a width of 0.2975m, and a height of 0.45m, and carried out model experiments under rainfall conditions. Body pore water pressure and displacement monitoring; Huang Ching-Chuan (2007) developed a landslide model experiment platform with a length of 3.94m, a width of 1.5m, and a height of 1.7m, and carried out a model experiment of slope degradation and failure caused by rainfall. G...
