MPTE [MPTE]

The aim of the Minimum Pile Tip Embedment Analysis is to determine the minimum pile tip embedment length that ensures lateral stability. A series of analyses are conducted by varying only the length of the pile. In Fig. 1a, a single pile is used for demonstration purposes. These analyses yield the curve in the Fig. 1b. y represent the total lateral deflection at the pile head. L_final and L_crit represent the final trial embedment length and critical embedment length for the pile, respectively. The curve in Fig. 1b. shows that the value of y remains unchanged for pile lengths longer than a certain length, denoned as L_crit. Total lateral deflection at the pile head are greater for pile lengths shorter than L_crit. Engineers typically choose a pile length slightly exceeding L_crit for specific applications.

This analysis can be performed using two types of models in OpenBrIM. The first model includes a footing and a group of piles, while the second model considers only a single pile. The process of generating these models is explained in the following sections.

• MPTE Model - Footing and Pile [MPTE]

• MPTE Model - Single Pile [MPTE]
