Practical DCP/PSP correlation tool for preliminary CBR, bearing pressure and geotechnical interpretation checks.
1. Paste DCP/PSP table
Type the interval once, then each DCP row. Initial depth can be written many ways, e.g. dcp2 start 200 3 3 4, id200 3 3 4, sd 200 3 3 4, or #200 3 3 4. Zero blows can be entered as 0. Refusal can be entered as r, refusal, 20r, or 20+r. Select DCP or PSP above. PSP mode defaults to 300 mm penetration and uses the PSP quick CBR option.
Material input: Add a general material line such as material sandy clay fill, or put material in each test row, e.g. CLAY 1 1 1, SAND 2 2 2, ROCK id200 6 6 6. Report wording will format them as CLAY, SAND, ROCK, Sandy CLAY FILL, etc.
Example input is shown in pale text. Click/tap the box and start typing or paste β the example will be replaced automatically.
Voice input is optional. Most users can simply type, paste, or use their phone keyboard microphone.
Saved input is stored in this browser only.
Zero blow counts are retained in the table. Converted CBR/bearing outputs for zero blows are shown as 0 and should be treated as indicative only.
Prototype only. Confirm the selected DCP correlation and calibration before professional use.
2. Cleaned table
Press Analyse DCP.
If more than four tests are imported, the cleaned results are automatically split into additional tables below.
Table follows your template: one penetration-depth column, then one pair of columns for each test. DCP normally uses 100 mm intervals; PSP normally uses 300 mm intervals. If a test starts deeper, cells above its initial depth stay blank.

Word and Excel exports are generated as real .docx and .xlsx files. The Output file name field controls Word/Excel file names and the PDF print title. Excel uses flat column headers so each DCP/PSP result aligns with its own blow/result column.

5. Profile graph
Graph uses blows, CBR, qall or qult on the X-axis and depth on the Y-axis. Each DCP test is plotted as a separate profile.
