Step-by-Step Guide: Calculating Soil Liquefaction in NovoCPT

NovoCPT is a specialized geotechnical software designed by Novo Tech Software to process, interpret, and analyze Cone Penetration Testing (CPT and CPTu) data. It automates the extraction of engineering parameters from raw cone measurements and provides modules for structural foundation and environmental risk analysis. 1. How to Import CPT Data

NovoCPT allows you to build a project containing multiple CPT soundings, which can then be combined with laboratory or secondary field data. Project Setup & Selection

Initialize Project: Open NovoCPT, click File → New Project from the top toolbar to clear any previous active memory.

Add Test: Click Add to prompt the data import dialog window. Data Mapping Configuration

File Selection: Choose your source text data file (commonly ASCII formatted formatted as .txt or .dat).

Define Columns: Map your input columns correctly. Usually, the columns are ordered as Column 1: Depth, Column 2: (cone tip resistance), Column 3:

(sleeve friction), and Column 4: u₂ (pore water pressure). If your file structure differs, manually assign the correct column indices.

Delimiters & Headers: Specify your column delimiter (comma, tab, or space) and define the exact number of Header Lines to skip before reading the actual test data.

Clean Data: Check the Remove zero readings during data import box to filter out corrupted or drill-out intervals automatically.

Preview & Execute: Review the target data matrix in the Data Preview window. Press Import to load the data into the primary processing engine. 2. Analytical Capabilities in NovoCPT

Once data is imported, NovoCPT processes the primary measurements to perform several geotechnical evaluations: Soil Parameters & Classification

Soil Behavior Type (SBT): Classifies soil layers automatically using up to 3 separate historical methods (e.g., Robertson criteria).

Parameter Correlations: Correlates raw readings into over 35 distinct soil parameters. This includes friction angle, relative density, unit weight, clay sensitivity, over-consolidation ratio (OCR), and undrained shear strength ( Geotechnical Engineering Modules

Soil Liquefaction Analysis: Assesses liquefaction triggering risk using established methodologies like Robertson (2012) or Idriss & Boulanger (2008). It also estimates post-liquefaction vertical settlement and lateral spreading.

Foundation Bearing Capacity: Determines allowable bearing capacities for shallow pad or strip footings using up to 5 individual structural calculation methods.

Foundation Settlement: Evaluates both elastic and consolidation settlement profiles over depth.

Deep Foundations: Estimates deep pile axial bearing capacity utilizing the LCPC method based directly on CPT tip resistance profiles. 3. Reviewing and Exporting Results NovoCPT – NovoTech Software
