6 FAQs about [Photovoltaic support in collapsible loess areas]
Are loess sites and foundations collapsible?
Currently, the research on the collapsibility of loess sites and foundations is mainly based on the traditional indoor collapsibility test (indoor test) and the in-situ immersion test (field test) (PRC MOHURD 2018).
Can geotechnical engineering models predict loess collapsibility?
The loess collapsibility data were provided from the Baoji to Lanzhou high-speed railway. The three ML algorithms are representative of geotechnical engineering modeling and are rarely explored for predicting loess collapsibility.
Can loess collapsibility be predicted faster and accurately?
To evaluate the collapsibility of loess faster and accurately, 300 loess collapsibility test data along the high-speed railway section from Baoji to Lanzhou were collected, and develop a direct prediction model for loess collapsibility parameters (see Fig. 1).
How do you know if a loess site is collapsible?
Currently, there are two types of tests used to determine the collapsibility of loess sites and foundations (PRC MOHURD, 2004). One test is the traditional indoor collapsibility test (indoor test), which is simple, efficient and inexpensive.
Does collapsibility affect loess engineering stability?
The compression curves of undisturbed loess have normalizable characteristics. A new method for calculating the loess collapsibility index is proposed. The calculated value of the new method is closer to the field-measured value. Collapsibility affects loess engineering stability.
What is a collapsible loess site under overburden pressure?
Therefore, based on the code (PRC MOHURD, 2004), test sites 1 and 2 are collapsible loess sites under overburden pressure, and their foundation collapsibility can be classified as grade IV (very severe) and II (moderate), respectively.
